My brother was in Vietnam in 1965. While there he took advantage of low prices while he was on R&R. He shipped home many, many things. The UPS man came to our house almost every day during the summer of 1965. Some big boxes arrived one day. I did my brother a favor by opening them and making certain everything was in good shape after being shipped thousands of miles. I found an AKAI reel to reel tape recorder and two large speakers that had 12" woofers and small tweeters. I had a Fender bass cabinet with a 15" Jensen speaker in it. My amp had blown so I decided to see if I could use the AKAI tape recorder as an amp for practice. I have no idea what the wattage output was on that AKAI, but my Fender Jazz bass sounded great going through the tube amp on the AKAI tape recorder into my Fender bass cabinet. By the time my brother got home from Vietnam, I made certain that AKAI was working well, although I never did play any tapes on it. My brother took it off to his apartment and spent a fortune on reel to reel music tapes to play on it, when lo and behold, 8 tracks came out.

My first guitar and amp was my dad's 1966 Teisco Del Rey EP10T plugged into a 1966 TEAC A4010S as a preamp which was ran through a 1967 Sansui 1000A stereo receiver containing this tube compliment: 2 x 6CW4, 3 x 6BA6, 1 x 6BE6, 2 x 6AU6, 3 x 6AQ8, 2 x 12AX7, 1 x 12AU7, 1 x 6BL8, 2 x 6AN8, 4 x 7591. The TEAC could be used to overdrive the signal into really thick fuzz. It was also LOUD. One day I pushed it too hard and toasted the majority of the tubes in the Sansui. Dad had the tubes (and something else) replaced and I was back in business.

The coil you found was part of the record and bias oscillator. It used the audio output valve (tube!) to form an oscillator when in record mode. Nominally about 30khz, higher in better quality units. This provided bias to the record head and also fed the erase head. In up market units a push pull circuit was used at around 100Khz often around an ECC82. The higher bias frequency gave lower noise and produced less distortion and harmonics.

This video reminded me of the good old days of just starting to play electric guitar. My mom had an old Sony reel to reel. I figured out how to use the VU meter levels and volume as a master volume setup for guitar. Have no idea what the model was; but it had speakers that mounted over the reel to reel chassis for storage. This was in the 70’s. I eventually got my hands on a pair of 4560 folded horn mid-low PA cabs that were loaded with EV Force 15’s. I actually plugged those cabs into the reel to reel with my ‘71 Gibson SG Custom. Sounded like shit; but, I was young and stupid. After that came a Marshall 100 watt 4-pronged half stack and the journey began. That setup was eventually stolen. I remember walking the SG home that night. Later that night, the Marshall half stock along with a mixing board I had was stolen. Man, those were some old days. 40 years later, got some fun toys now (Marshall JTM45, an 18 watt TMB Head, and an original vertical input JCM 800. Been through all kinds of different amps in between. Can’t even recall what happened to some of that older transitional stuff. Fender, VoxAC 30, Legend, Park, full circle and back to a trio of Marshall’s again.

Good resurrect for that tube amplifier, good sound. Those shaded pole motors with the extra take of winding to feed the amplifier is not always a true isolation transformer. Often it is a tap of winding at a specific voltage for the amplifier. That voltage could have been perhaps 60 Volts AC. When applying 110 Volts to the amp it caused the series resistors to burn up and tubes glowing like a light bulb. Old tube turntables had similar arrangements as well.

Just as I started to doubt my first tube amp build would have any power you post this. Had an old tube amp from a record player that was built into a case of a film strip projector. It's a series filament with a 12AX7 and 2 50C5 tubes. This amp was modified 2 or 3 times the rectifier tube was replaced with a Federal ITT. 1005A selenium rectifier at that time the 35C5 tubes where replaced with the 50C5 tubes, the cap can was replaced with 3 caps and then selenium rectifier was bypassed with a silicon diode. At the time I could not find a schematic for this amp so I'm building an amp using the schematic for push-pull with 1 gain stage of the 12AX7 and the other as a cathodyne phase inverter. The schematic I'm using is just called AC/DC Amplifier. For this build I'm looking for a clean amp for a acoustic instrument.

Hey Brad! Just watched this video. I would like to have seen this restored, but after seeing the trouble in trying to replace the belt, I can understand your decision. The manufacturer apparently didn't make this unit easy to service! I looked up the manufacturer of the Ceracap capacitor, American Radionic Company. The company WAS located in Danbury, CT. In 1987, the company relocated to Palm Coast, FL. It is now known as AmRad Corp. Except for the motor/transformer and the four-tube complement, this tape player/recorder looks very similar to an AA-5 design.

Wish i had been in this one when it was first posted. I had a Telectro R-R i found in the trash back in the early 70's. It was a cheaper version of what you have of you can believe that. It was a one speed I used it to record songs we were going to do in our little HS band. I had one R-R for each guy in the band. It was a wise decision to not repair the tapepart of that unit as they were pretty crappy when new. I think i see a permanent magnet for the erase head. That's your first clue it was really just made for the average consumer to novelty play around with at home. I'm sure the wow & flutter even when new was horrendous. Anyway, good thing you got your$20 back out of it cause even as a working reel to reel it is worth less than $20. To make it a tape delay would have been an interesting idea with built in flutter😂. Very fun to watch the whole process. Very much enjoy all your efforts and education.

I'm myself fighting with a tremolo pedal right now for about a week, specifically a buffer gate section which doesn't want to switch transistor properly without polarised caps, and i don't want to have a polarised caps in there, yet with polarised caps (non pun intended) it works perfectly, so maybe i should just proceed with that.

I doubt that's why you have little gain. It's probably just a matter of the circuit being maximized for low distortion and high fidelity rather than guitar use. It could be you also need one extra preamp gain stage to really take it over the top.

What about building a PWM amp to replace the amp that tape deck and possibly use the tape mechanism as a tape loop reverb, a NE556 half used as the clock the other half used as the Pulse Width Modulator clocked from the first half driving MJ3055 TO3 case transistors driven via a BD131 driver Transistor whose collector connects to the base of the bottom MJ3055 as well as a 10 K resistor to VCC and a 47R resistor from the emitter of the BD131 to GND and the output from the MJ3055 goes through a lopass filter back to emitter resister via a 47K resister, the base of the BD131 gets driven via the second half of the NE556. I guess you are wondering about the two MJ3055 transistors well a 1K resistor connects between the VCC and the base of the top transistor then to the collector of the bottom transistor via a IN4007 diode and a matching IN4007 connects between the emitter of the top transistor to the collector of the bottom transistor, the emitter of the bottom transistor connects to GND or negative the output to the speaker via a 10,000uf electrolytic connects to the emitter of the top MJ3055 and also connects to the lopass filter that feeds back to emitter of the BD131, I would have attached a diagram but KZbin doesn't allow you to add attachments into the comments.

If I got to choose, I'd keep the top of the volume control oscillation and add a pot for bias to get the double action - dime the volume and start playing synthesizer!

Just MHO, but I think I've heard you say it yourself in the past...'the world has enough guitar amps'...if you can bring this back, I think that would be a laudable endeavor, and hopefully profitable at some point...

It sounds nice enough to become a head even if it does have a very old style sound. It really needs a tone control section though.

No doubt, make an echoplex-ish thang. With the price of effects being as high as they are, you could swap out to some general/generic tubes and make some player or yourself totally psyched. Or... make it an amp or go back to orig. Lol, was that helpful? I feel your pain with this decision. Good luck with your back duder, walking is great back healing therapy

I'm thinking small amp. Hey Brad they were mentioning you on a Tone Talk vid the other day featuring Mr Egnator with Marc and Dave. All you need now is a small box and some old beat tweed. Love your vids.
@TheGuitologist7 жыл бұрын
I saw that. None of them knew who the hell I was...even though Bruce Egnater is in one of the amp groups I frequent. It was good for a laugh. What's his name, Phil Knight, was asked about one of my videos too not too long ago. I only know this because one of my viewers pointed it out. He called me "the guitar-ologist". :D

Hmm. Keep it as an amp. Install it in a vintage makeup case. Then list it for sale. Id live to have it. Plus I'm in Kentucky so I could pick this sucker up. Love you videos by the way. Rock on.

It would be awesome to see you convert an old cassette machine into a tape delay with variable speed. Many people have done this with the Marantz portable cassette I believe.

Every now and then I'll run across a cool tape deck I'll pick up. Maybe I'll venture out into something like this and do a video.

Up here in Halifax, Nova Scotia, I recently went to a Fix-It Fair where I met Dr. Dan, a fellow who builds new vintage-style tube amps and repairs tube amps like you. I told him about your channel and how the one thing I learned from you is “replace bad caps.” When I said that, his eyes lit up and he began to vent about his customers who wouldn’t let him do it because they wanted all-original parts.

@TheGuitologist7 жыл бұрын
In some cases I do that, at least on parts of circuits, to help visualize what's happening, but in something like this, it's more a matter of deleting what I know for sure doesn't belong and putting in there the stuff I know should go, then tweaking around the issues.

I say make it into a Recorder\Guitar amp and delay echo unit and maybe add another one or two play heads like a Watkins copy cat with a feedback control, I love this I grew up on these recorders I have a collection of similar tape recorders.You know you can do it.

Hi Brad, Could you have taken the spinnie part out of the motor and still used that as an isolation transformer?
@TheGuitologist7 жыл бұрын
Probably could have done. That is a good motor though. I'll definitely use it in something one day, and it's nice that it doubles as a 1:1 transformer.

Wasn't possible on this without a lot of re-engineering. Not enough heads or triode stages.
