Insanely Rare Roberts 8-Track Player

Hz not MHz!! This Roberts 848X was located at an antique store when I found it. Peering into the spy window on top of the machine, I noticed a very odd configuration of tape heads, pulleys and levers. Here is this incredible 8-Track tape playing machine that I'm guessing came out in the late 60s.
Electricity runs in Hz, not MHz. Just a minor correction there.

Queen on 8-track? “Thunderbolt and lighting, very, very frightening!” *KA-CHUNK*

[@michaelshultz2540]

Roberts aka. AKAI was always at the top of the consumer/professional audio industry. Setting the standard for the rest!

[@gavincurtis]

I believe that head on the left is the erase. It has only 2 wires and conected to that nearby coil that is probably the oscillator for erase. One hell of a find.

[@eggman09]

I think you're right Dollar Guy - I believe it's "cross-field" head system also used in Akai and Roberts open reel machines of the period. It was supposed to be superior (for some reason I can't remember).

[@airplaneengine]

I honestly cannot believe you found one of these! I remember reading in an early 70s HiFi/electronics magazine about the development of an 8-track machine that was supposed to draw the tape out of the cartridge. I never thought anything like it went into production as I've never seen any pictures or examples of such a machine! I would almost be surprised if that isn't a prototype. I can see the issues it would have with being rough on tighter tapes that just don't have the slack in the tape pack. Glad you got it working. Take good care of it.

[@airplaneengine]

There are a number of 8-track deck models that have play/stop buttons/keys. Many of the Akai/Roberts decks (with similar build quality, large motor... as this one above) have play/stop/FF/record buttons.

as a notorious akai collector i felt something was similar=)

[@xaenon]

See, kids, 8-Track really COULD sound good.

[@danieldaniels7571]

I’ve had several 8-track decks over the years that have sounded good, and some were very basic. Half the battle is head azimuth.

[@xaenon]

@@danieldaniels7571 Yes indeed. The older players always seemed to be better built and less problematic. In the early 1970s they started cranking out cheaper players and those were the ones that would seem to knock themselves out of alignment more readily. Of course, that was also right around the time they started taking shortcuts with the cartridges, too.

[@danieldaniels7571]

xaenon Some of those cost cutting moves with the tapes really brought down performance, like hard plastic pinch rollers and cheap foam pads as opposed to felt on springs. Not all the later players sound bad, though. I have a basic Realistic that was made in the ‘80s that sounds surprisingly good. It does knock itself out of alignment and need adjusted regularly, but it’s design makes that simple and easy without the need to open it. What gets me is that no one (far as I know) ever made a high end player with a stationary 8-track head.

[@xaenon]

@@danieldaniels7571 My speculation is that It would likely have been a very expensive thing to do. The common 8-track tape head is a pair of pickups in a housing for 1/4 inch tape. For a stationary head, it would require EIGHT pickups in that same housing - that's a fair bit more expensive. Even a pair of four-track heads in an offset configuration would be more expensive. The whole idea of 8-Track was it was supposed to be for 'everybody' and that meant affordable, and if you start throwing expensive hardware into your product it means the price has to go up. THAT, in turn, drives the price up, and while what you're offering really is a superior product, everyone else is going to be selling a cheaper product that does basically 'the same thing', just in the older, less sophisticated way. And let's be honest here. It was the EIGHT TRACK. This was a format developed specifically for cars, and at the time of introduction, aside from providing you with the means to select your own music, only had to do one thing: Sound better than AM. FM wasn't all that common in cars when the 8-Track came to market. By the time there was really a call to improve the 8-Track, the cassette had already been vastly improved with the new CrO2 formulation and could turn in pretty good performance... and from a smaller, more convenient format. By the mid-1970s, the 8-Track was very much seen as 'riding off into the sunset', so the manufacturers weren't willing to throw money into trying to improve the format. The only real reason it stubbornly hung on for another decade or so was because it was so heavily entrenched - lots of cars still running around with 8-Track players, lots of home stereos still sporting 8-Track decks, lots of tape cartridges still in music collections. Sort of like how record players retained a '78' speed setting well into the 1970s (and many newer ones today feature it!), even though the US hasn't had a significant production of 78s since the mid-1950s.

Awesome machine.....I would love to have one of these. No telling how many times i've run across tapes with bad pressure pads and with a machine like this, you don't need to worry about them. Plus, it looks nice as well!

[@AttilaSVK]

The other head is the crossfield head (that's what X stands for in the model number). Basically, bias frequency is not mixed with the audio signal during recording, but instead is emitted by a different head, positioned at the back side of the tape. The technology was used only by Akai (a.k.a. Roberts) and Tandberg on reel to reel decks and I've never seen it implemented in an 8 track recorder. The crossfield technology offered lower distortion and higher quality recordings, but it was much harder to align, and eventually both the heads and electronics got better, eliminating the need for this technology.

[@RyanSchweitzer77]

Thanks for the explanation, I always wondered what exactly the "crossfield head" technology was that Akai/Roberts/Rheem decks used. I've come across several of their open reel decks with it.

[@johnpratt2045]

If you watch the way the tape threads, from around the 12 minute mark, you can see that the other head does not come in to contact with the back-side of the tape. Therefore, it cannot be a cross-field head. Furthermore, if this were a cross-field head, where is the erase head? That means this is the erase head.

[@AttilaSVK]

@@johnpratt2045 yes, you are absolutely right. Also, a cross-field head would contact the tape from the rear, not from the oxide side. Then my remark about the X in the model number standing for cross-field is also irrelevant.

[@johnpratt2045]

@@AttilaSVK In Akai's reel-to-reel tape recorders of the era x in the model number did indicate that, so it was a perfectly reasonable assumption. Perhaps "X" in this case indicates it was experimental or some sort of engineering sample.The lines scribed into the metal of the rear panel marking the hole-drilling positions, from the 6.35 minute mark, seem unusual for a product that was in production. I wonder if any more of these have surfaced?

[@RuneTheFirst]

That mystery head is probably the bias head. Akai was using "Cross Field" bias in those days where the bias was applied via a separate head that swung into place across from the record pole pieces, Combo record/play/erase heads had been available since at least 1964 and had become almost universal by the end of decade.

[@EdgarsLS]

There would have to be an erase head, the record head wouldn't erase the tape enough and the previous recording would be heard afterwards. but it could be the case that they are intentionally putting the erase head so close to the record head so that it both erases and also biases the record head.

[@RuneTheFirst]

@@EdgarsLS Akai did use separate bias heads until 1972 on many models. So did Tandberg. If there is an "X" in the model number it is guaranteed to have the separate bias head. It is the whole reason for dragging the tape out of the cartridge. I didn't say anything about not having an erase head. There was always an erase head.

[@BrokebackBob]

Quality bank vault build. Roberts was a very high end tape equipment manufacturer for decades. I think you should have a dignified service for the Roberts and let it pass into the universe.

[@dashcamandy2242]

I can confirm the quality of Roberts. I have a Roberts Rheem reel-to-reel that I inherited from my father; it has NEVER been serviced (although it's on my to-do list) and it works perfectly aside from the volume pots needing a brief spritz. The crackle is almost nonexistent. They just don't make stuff with quality like that anymore...

[@dennisbowsher6267]

Hi. Denny Bowsher here. The extra head is the famous Akai--same same Robert's, "crosfield bias head that greatly increased the high frequency recording capablity of the tape. This was a truly great tape machine and was unique to Akai as in my 1800SD machine.

[@adrinathegreat3095]

[@riverhuntingdon6659]

What a strange creature, but a very high quality one. Can't say I've ever come across one of those. Talk about over - engineered to last forever ! Thanks for the upload.

[@jamesbennettmusic]

Not sure if anyone else has mentioned but I think that extra head is for recording bias, not erase. The X in the model name is a giveaway. The method is called "cross-field bias" and was licensed from Tandberg in the 60s and 70s. Roberts, Tandberg and Akai all featured it at one time. For slower tape speeds, it's supposedly a more "accurate" way of applying the bias, by offsetting it slightly from the recording gap. I once had a Tandberg open reel deck that had it, and it was effective to a point... The problem was that alignment could be really difficult to keep steady and would vary with different tape coatings and thicknesses. In the end it was dumped for improvements in circuitry instead. (And now I'm seeing comments about this machine being built by Akai, so yes, I'm pretty sure it's a separate bias head)

[@johnpratt2045]

If you watch the way the tape threads, from around the 12 minute mark, you can see that the other head does not come in to contact with the back-side of the tape. It runs against the same side as the play/record head does. Therefore, it cannot be a cross-field head. Furthermore, if this were a cross-field head, where is the erase head? That means this is the erase head.

[@RuneTheFirst]

@@johnpratt2045 It can be both. "X" always designated "Crossfield" in Akai-made stuff.

[@thiesenf]

50Mhz or 60Mhz mains frequency... MHz??? That hertz...

[@GTI1dasOriginal]

(being midway in the video) It's an Akai. See the "old style" "A" logo on the PCB shown at 1:03 Rebranded and / or made in corporation with Robert G. Metzner. The X stands for "X-field" (cross field heads) being a predecessor of the GX (Glass X'tal) heads. You can see the "dual head design" at 09:58 It only used it's "secondary head" when recording. The Crossfield principle being: a second (opposite) head was needed in order to record in better soundquality (upper bandwith: 10 kHz - 20 kHz), it provides the needed bias to recording, so it's not an erase head, it actually increases soundrecording quality. An 8 track tape doesn't allow a second head behind the tape (due to design of the physical cassette itself) thus the tape needed to be "pulled out" in order to accommodate the crossfield head. Some of the switches / knobs used come directly from the akai X-330 D RTR recorder (1968) The exact same "vent design" is also used on the akai AA-7000 / AA-7000-s (1968 - 1973) Your 848-X has a build in amplifier, so it indeed could be used as a "stand alone" deck, plug in a set of speakers and you were done. In "akai terms" it would've been known as a "non-D" deck, so it would imply that there also would've been a Roberts 848-X D version at the time (not sure)

[@doningle6137]

The other head is definitely an erase head! At first, i thought Akai/Roberts had devised a way to add 'Cross Field' recording to an 8 track. Still, since this doesn't rely on the cartridge pressure pads, or the azimuth of the cart to be correct, this would produce a superior result from a pre-recorded tape, and likely make some awesome sounding recordings as well. With the machine controlling the tape feed and head wrap, this would also reduce wow and flutter significantly. With the capstan in constant motion, this also improves tape start up, particularly for recording. An amazing machine and I would love to find one of my own! Great find!

[@therealjammit]

The record head you mentioned only erases the tape before it passes over the "play" head (which is now acting as the record head).

[@FeCr3]

That looks like a Perfect 8-track mechanism !

[@MVVblog]

That system make the tape run against two fixed posts that scrub the tape and can ruin it. Anyway it sounds very well. Very unusual drive system for an 8-Track machine :-)

[@danieldaniels7571]

I was thinking that myself, but it’s really less harsh than what the tape has to run against inside the cartridge, and 8-track cartridge tape stock is sturdy with a dry lubricated backing.

[@Bob-1802]

Just a thought regarding the BB. Maybe when you had or someone else had replaced the belt there was some type of bearing ball there already, but when it was being disassembled/repaired it fell and no one noticed. Just a possibility. Great mechanism for feeding the tape to the heads. How come there is no FF button? Most 8 tracks had at least FF. How do you reset the tape counter? Did not see a reset button. Is there a glass or plastic cover over the window to the heads and counter? Thanks for saving this machine and giving it new life.

Because of the lubricant used on the back and having to be tough enough to survive an endless reel cartridge, 8-track tape stock is very resilient.

[@bob7872]

A nice tapedeck. I like the idea they used so it wouldn't need pressure pads.

[@jhonwask]

I wonder why they didn't keep up with this particular transport and play system. It could sound as good as an open reel deck.

[@CassetteMaster]

That is a most incredible, excellent 8-track machines!! I believe it is a separate erase head and record/play head. They did have single erase/record/play heads (really two heads in one head container) at the time, but I believe they separated them out as this is a higher end machine, and probably (perhaps) to have slightly wider tracks on the erase head than on the R/PB head to better erase previous recordings (many times in my 8-track heyday (2005)) the erase did not do so good with alignment with the original recordings and the old recordings would bleed through if the azimuth and alignment was not really good. The pausing is good, as the motor pulling the tape when not in play mode is an annoying thing. The one thing that would have made this even a better unit is if the 8-track pinch roller was slightly pushed away from the capstan for pausing (the Realistic TR-801 is like that, so you have a smooth starting and stopping with its pause). Have you tried making any recordings on this unit yet?

[@SarahRWilson]

From the days when they built gear with more metal than plastic. There were some observations made about the head compliment, that it was based on the same cross field technology Akai used in their open reel decks. I too was about to come to the same conclusion when I saw the heads come together around the 10:45 mark. Then I wondered how they could do cross field effectively through two layers of tape. Never mind the problems with having both layers of tape in contact with each other, and moving at opposite directions, but I digress. What counts though is when tape is loaded and moving. This is seen around 11:50, and shows the head on the left side of tape path being held in place by the tension of the moving tape. Hence the head on the left side is merely an erase head. The physics of magnetic head design dictate that cross field cannot work across a gap that large, and any magnetic field intense enough to try would affect the other tracks on the tape. As to resetting the counter, there appears to be a lever over the counters reset button, but it's unclear how it's activated. Maybe Techmoan can answer that one when he does his video on this deck. ;-)

[@danieldaniels7571]

I’m still waiting on that Techmoan video

Sounds incredibly good for an 8-track player. The main problem in this format was the pad and this device bypass it. It's interesting to know if there's a risk of damaging the tape like some VCR's, otherwise this is best 8-track player (and recorder) ever made.

[@hicknopunk]

I have a wood sided Akai tape deck with the same lazy pause. I love it!

[@JayRudko]

The "X" in the model number indicates crossfield heads. The head that moves into place when you press "record" applies the bias signal when you record, which is the same idea as what they used on reel-to'reel decks like their 770X deck. It allows for better high frequency response when recording.

Any ideas what this issue could be?

[@equid0x]

Not familiar with the unit, but VCRs that exhibit this issue typically have a problem with the IR emitter or detector used to detect end of tape. Next thing I would check would be the mode switch.

Now if they had extracted the tape far enough to use its own pinch roller rather than the cartridge's own roller, it would have been fantastic! Really it bent the format a bit because there's a risk of getting tape slack.

Great 8 track machine solid State

[@TonyP9279]

I'm not sure if that's a good design. Pulling the tape out like that tends to unspool extra slack within the cartridge. When you press stop, the pinch roller is literally pushing the slack back into the cartridge and does not wind back onto the reel.

[@AudioFileZ]

Back in the early seventies I had a Wollensak 8-track recording tape deck. I always thought the Wollensak was the best, especially the later version that added Dolby B. The fidelity of the Wollensak was pretty good for the format. I'd like to know how this deck with it's unique tape to head isolation mechanism compared to the Wollensak ones? I added an outboard Teac AN-60 Dolby B unit to mine and I thought I was pretty cool as a young teen. By the late seventies the writing was on the wall that 8-track was passing with the quality of the compact cassette ramping up. While in college I switched to cassettes and like my bike when I got my driver's license I never looked (or listened) to the Wollensak again. I've been a tapehead since I was about 12 years old when I bought my first quarter track reel to reel. That was also a Wollensak unit and I remember being in middle school anxious to get home to play with it. I got it from a company few remember called Burstein & Aoolebee who specialized in liquidation of electronic gear as well as parts. I loved reel to reel so much I bought a Akai 4400 the summer before my senior year in 1976. How much did I love it? Well, my folks let me and my three best friends go to Panama City Florida on summer vacation loosely being chaperoned by some adult family friends who were actually there because one of our high school sororities called Ad Astra rented a house on the beach for the Ad Adstr gals. I took a receiver, my reel to reel and one of my friends brought a pair of Dynamo A-25 speakers. We were on the second floor of the not so famous Casa Loma Motel... so with the electronics in our room I ran speaker wire over the balcony and down to the pool where we had the Dynamo speakers for a pool party that lasted about an hour before we were told we'd have to stop! That's how much I was into stereo gear , tape recording, and music in general. Crazy in every sense of the word. We took the party to the room and got away with that for some reason! So, I'm a tape nut who wasn't averse to loading up my gear for whatever...and I still have a Pioneer 1020 R2R and multiple cassette decks. I thoroughly enjoyed your video on this unique deck. I'd still like to know if the frequency response and the signal to noise ratio of this deck was better than my old Wollensak, which until now I thought was the best ever made.

I'd like to see a review of the original MP3 cassettes like the MobiBlu and others from that era. Compare to the one or two crappy ones currently available. The very first model didn't have an SD slot, but the company quickly introduced a 2nd model with SD.

Listening to the camera feed over a mono smartphone speaker, I can tell there are phasing issues with the audio.

Really beautiful machine from time when audio was played mechanically, not like today when everything fits in single boring chip. One thing is interesting @18:42 it is written "OUT PUT" as two words. I always thought that you would write "OUTPUT". Did that changed in the past 50 year?

I think that some products have it as two words but others have it as one. Maybe it was to feel more proper? Or just be a different
