BK 1077 Television Analysis Diagnosis Repair

vintage tv test equipment repair

[@byrnejr]

I have no tv or radio experience... I collect old tube radios and have learned a tremendous amount from you! Thanks for sharing

[@RichardHartness]

Other than the original CBS test pattern tube that ws donated to a museum, this is the coolest piece of hardware I’ve seen on this channel. Thanks for sharing.

[@Musicradio77Network]

I remember the WCBS-TV test pattern. They were part of NYC TV history where they used it during sign-offs.

[@waltschannel7465]

These Analysts are neat, that's for sure! I had a model 1076 (the earlier version) from 1978 to 1999. Just couldn't justify the space in my small house anymore. Still regret getting rid of it.

[@qzorn4440]

very nice This is what we used in Vo-Tec 1968-69 TV repair. 🥰It was and is wonderful. 😎 Thank you.

[@stevencarlson5422]

I love the look of the old set in the end what a beautiful design and color

[@perrymckinney6146]

That picture on that tv reminds me of the picture we had on our first color tv as a kid, the tv was ran from morning to night and the life was sure ran out of the crt. Got used to watching it like that, there was no emission left in the green gun, red and blue weas super weak. We has to close the curtains to watch the thing. We got our second color tv and WOW! All the colors and it was BRIGHT ! That was the days before I was in to tv repair.

[@scharkalvin]

The CRT / Photo-multiplier tube is the basis for a flying spot scanner. That's probably a 5FP7 dual phospher tube that has a Blue/UV phospher driving a long yellow one. Hams used to build FSSers for SSTV use. Sometimes a slide wasn't used, instead the CRT illuminated a positive image (photo) and the reflected light was read by the PM tube. In this case, two PM tubes were used, each looking at the card at a 45 degree angle and their outputs were combined. Those 931 PM tubes, and the surplus 5FP7 radar tubes used to be dirt cheap, but for some reason they seem to have become 'rare' and now go for a higher price. BTW, that 5" CRT only needs about 5KV NOT 15KV! Some variants of the 5FPx tubes were made with an aluminumized screen, they wouldn't need the ion trap magnet. If the tube suffix ends in "B" it is an aluminumized screen.

[@DanafoxyVixen]

I think your quite right, the CRT voltage should be lower for such a small screen. Is it me or was the CRT also meant to be a little brighter? maybe the ion trap magnet might be slightly out of alignment

[@survivalcomms]

There was a whole soulfulness to consumer electronics repair that is so under appreciated today. The irony of watching disposable cell phone advertisements through a DTV converter on a vintage set is not lost on this viewer. Thanks for sharing !

[@Rainbow__cookie]

We need more people like you crts is underrated

[@racecar_spelled_backwards868]

WOW! You put the REAL star late in the show! That Magnavox is a beautiful machine. I hope she has many years and lots of good watching in her future. Hey I like to be an optimist. The my auntie's house was done up in that late 1960's faux Asian style. It's an acquired taste, but if done correctly can be quite pleasant.

[@craignehring]

Nothing could be finer than a Monday morning Shango066 video

[@dstoll7958]

Every Monday @ 7 AM pt I tune in to see if he has thrown us a bone for the week. Never disappointed. He is the favorite UHF channel that played Looneytoons in the afternoon- after school when I should have been doing homework.

[@craignehring]

@@dstoll7958 HA Haaa yep!

[@abc-ni9uw]

Basically another wet rainy day in London England. Love the video s66

[@dstoll7958]

The old Magnavox still even has the plastic twist locks for easy removal of the back. Very cool!

[@circuitsmith]

We had one of those in a shop I worked at in the mid '70s. Oh the memories!

[@MrChief101]

Pretty cool piece of test rig. And a rather zippy diagnosis. Love the historical material-- those were slower times indeed. Just gave us more time to get into individual trouble!

[@harshnemesis]

The tv at the end is good because if you "accidentally" smash the tube, you can just close the doors and pretend it never happened :D

[@BetamaxFlippy]

Shango doing a full recap? Someone call 911

[@luisreyes1963]

Ancient technology never fails to amaze me. Keep up the good work, Shango066! 👍

[@kensherwood4866]

Thanks for showing and explaining the details of this device. I'm not an electronics expert but I do enjoy watching your video posts, the old tvs etc. Thanks again

[@joeblow8593]

19:45 I didn't know you can swear in Japanese lmao

[@Trev0r98]

Another great vintage TV analysis and diagnosis video by *Roko Shockyotch Fazhaza Lairmo* . Nicely done!

[@chuffpup]

Learn something new every time I watch these. It's such a neat little machine too. I really like the the crt and scanner tube arrangement. Very funky.

[@Synthematix]

Beautiful piece of technology shango.

[@TheRadioShop]

I have a 1077 in mint condition. I need to get it out and play with it more. Thanks for sharing your troubleshooting skills.

[@beamfinder8336]

Very nice device

[@christinecortese9973]

I’m old enough to miss actual letters and notes. Love physical stuff. Yes it’s easier and more efficient now but those are not always the highest values in life.

[@nikelquint]

Those letters are mega-cool… Really neat the previous guy kept them

[@GrandsonofKong]

I've got a BK 1076 I picked-up for $5 someplace. Too cheap and too cool looking to pass up. One of these days after the other 150 projects get taken care of...…..sigh.

[@volvo09]

Cool fix, keep er' out of the metal scrap pile.

[@5roundsrapid263]

13:55 It blows my mind, too! People were more patient and polite when they actually wrote letters...

[@cardboardboxification]

People are going to loose their minds when their atm cars doesn’t work, and their phones with internet is taken down..

[@equid0x]

People were taught "common courtesy." I hate to sound like an old fart but people really don't have any respect for each other anymore.

[@5roundsrapid263]

equid0x I work in retail. Surprisingly, the younger generation seems to be more polite than middle-aged adults.

[@equid0x]

@@5roundsrapid263 I didn't really want to call anyone out but there is a certain generation I have in mind that generally has entitled attitude and it's not the Millennials.

[@5roundsrapid263]

equid0x I agree. These are the ones younger than the millennials. Post-millennials?

[@robinsonsoto8471]

Hello. I do like your Video. Amen

[@JerryEricsson]

Love that black and gold cabnit. I would love to have that with a full size LCD TV inserted where the Magnovox is.

[@wecontrolthevideo]

After you hooked up the converter box and before you fine tuned , that was the first time I have heard sync-buzz in years .

[@paulsontag9233]

That 68 Magnavox a work of art.

[@margaqrt]

I got one of these analysts for free at a swap meet in July. Neat to see the correspondences from QST. Thanks and 73 de KE0RFZ.

[@Mr_Meowingtons]

i would love to see it after the recap.. nice pice of tech history

[@XMguy]

Gath I find nothing. The address is now a payday loan place. Sad.

[@INRIKingOfKings]

I have been on the hunt for a 1077 and the 415 for years but yet to find either. Ebayers think they are worth a fortune and then there's the ridiculous shipping fees that every Ebayer thinks they need to make a profit on the shipping. And as for repurposing the vintage tv's. That really yanks my chain. Those too, I am always looking for and they are extremely rare down there in the South. Great video by the way.

[@williamsquires3070]

Yeah, I’d like to substitute most of the signals you get with crap-o-magic cable TV with something like these videos (and others by radiotvphononut, 12voltvids, bandersontv, etc...) Even the test signals put out by the B&K are more intelligent than the mind garbage on TV nowadays. Can shango066 do an EOL video on actual CATV programming? 🤣😝😆

[@rdsledge]

That console TV cabinet is really cool looking. Thanks

[@fredfabris7187]

Old sets are like cars with carburetors and points.

[@TheSoundrookie]

Well, we may ask ourselves how people got things done back in the 80's, but the fact is that they did, and it was far better times than now. If you by chance should invent a timemachine, and need a guinea pig for the first test trip back in time, I'm on. Just give me a heads up.

[@69Dartman]

I tried to collect anything like this I could back when I was actively fixing TVs. I mainly ended up with crt rejuvinaters and new and old tube testers. I have a nice suitcase tube tester, a couple of the old military 177b units that will test almost any tube ever made up to the mid 50s, one has all the extra tube socket adapters and updated manuals, and at least one from the late 30s. I have all kinds of weird things I've collected over the years and all those tubes I collected back from the mid 70s up. Guess maybe I should see which ones are worth money these days and start selling them off.

[@orange70383]

I amazed that you were able to quickly locate trouble spots so precisely using methods that at first glance look to be at best completely off the wall yet seemingly carefully honed, interesting.

[@hestheMaster]

Gath TV and Appliance building still there. It's a Furniture and Mattress store now. Total recap and don't forget that tall silver can! Great save,never going to the dumpster! You know that Magnavox console TV would look good in any mid-century home in Palm Springs CA! Maybe someone there would like it if they have a fire extinguisher handy! Medullary Thyroid Crystals out!

[@isoguy.]

Cooke-moona-bloover, where do you get those names from? Laughed till I cried. Another fantastic, interesting, informative, Cooke-moona-bloover, awsome video. Both this channel and your mine explorer one are mandatory viewing; absolute best Vids on the tube, thanks for sharing. 👍 👍 👍

[@isoguy.]

Awsome man.

[@danmackintosh6325]

Happy Birthday Kookmoonerblouver...

[@hotboiorlando]

i like that tv at the end i just wish i had a way to get it here to me

[@a4000bear]

I'm actually in the middle of restoring one of these. I have the version with the ICs. The CRT is not identified in the documentation I have, apart from the B&K part number. I suspect it has a P16 phosphor as it is purple/UV colour and very short persistence as required for flying spot scanning. The documentation also specifies the EHT for the CRT is approximately 12.5 kV, I get slightly less than this in mine (which has the aluminised CRT). I'm in Australia, and had imported my BK 1077 from the US, so I have to use a 230-117 V converter that also converts frequency from 50 to 60Hz, as the BK 1077 uses the mains frequency to determine the vertical frequency. I have also experimented with a divider circuit that I added to the existing IC divider to also generate a vertical signal that is referenced to the 189 kHz colour bar, giving interlaced video. There was a PAL version made for Australia, I have seen advertisements for it in old electronics magazines, but I have never seen an actual PAL unit.

[@johnsampson1096]

Shango, couldn't see all the documentation you had on this, but I have an original instructional manual for this one if you don''t have or need one . Let me know and I'll send it to you. Least I can do for all the quality videos you send out. John

[@ricknelsonm]

LOL, the cell phone comments, lol

[@turle8645]

The magnavox sets have really really good sound

[@superhet7281]

What you need is the B+K Television Analyst Analyst. The Analyst Analyst is used to troubleshoot the Analyst (yuck, yuck!).

[@weirdbeard63]

A guy I know cleaned out his garage and shop and filled a 30 yard dumpster with all kinds of electronic stuff. It's all gone now. I may never forgive him......

@ 24:34 medical glossary tourette's kicking in, eh? Nice maggotbox! Thanks for the memories.

[@patjones8598]

Interesting it mentions PAL system in the manual need to look into that some more and see if it there’s a version that works with 405 line sets

[@equid0x]

My great grandparents had a Magnavox almost identical to this but the chassis was blonde and not black. Had the rollout doors and everything. Not sure what happened to it but probably went to the dump when they passed.

[@Rev22-21]

A friend of mine scored two of these and has them in storage now. They came from an estate sale as well.

[@hotboiorlando]

i would watch the price is right on an old tv like that just for fun

[@foxrivers]

If you're looking to get rid of sets I'll consider something that isn't longer than 6' whatever will fit in the back of my boxy Scion. I work on slot machines in Vegas and I'm trying to get more acquainted with CRT tech.

[@ShannonMoskowitz-v5p]

Is it best to leave in the original box and packaging or open and test for functionality? The seal has been broken…but never removed from box.

[@Rfk1966]

Was this from the estate sale in San Jacinto? You guys did pretty well that day

[@davepike6170]

Great work, Shango066! If you ever have any duplicates of the slide set, I'd be interested, I have a good working 1077B, (after I re-capped it), but I only have one slide. It's the best piece of diagnostic equipment I have, it's helped me often in subbing vertical and horizontal signals. BTW, I know where Memorial Pkwy is, in Huntsville, AL! I have relatives near there!😊 Nice Oriental Maggie, and I like seeing your cat go by! My kitten is currently playing with trying to catch the image, as you pan on the Maggie chassis, as I write this! Cheers! Dave Pike "Bigdavestv"

[@christopherrasmussen8718]

That manual is priceless

[@gregoryclemen1870]

yup!!!, those color sets were known for flyback transformers going up in "SMOKE", and the fire department would be called, and they would take your prized possession out to the front lawn and proceed to douse it with water( plenty of it too!!! ). then I would get it for repair, and just about all of the output tubes would be cracked from water when the set was still hot!!!. then you would give the customer the estimate for repair, and watch their jaws drop, and the blood run out of their face. then the set would become a "PARTS" t.v. set( not repaired )

[@gerardcarriera7052]

I'm surprised that B&K unit is a series string tube circuit. You'd think something that intricate would have a power transformer. Regarding the Magnavox, either it doesn't have instant on or someone made the right decision to switch it off. Maggies from that era often have cooked CRTs.

[@mikereid680]

I would love to adopt one of your consels. I live in Lompoc Ca my name is Mike. Just love the old electronics. I grew up with stuff.

[@DAVIDGREGORYKERR]

I have have seem a triple standard Set like this you know 405-B/W,PAL(625) and NTSC twice the size of that one.

[@coyote_den]

Tubes all the way through CMOS logic... did they just throw whatever parts they had lying around in that thing?

[@jrs0007]

Back in the day... No internet, pay-by-the-minute "long distance" phone calls, typewriters, dot matrix printers, and Air Mail. Never could afford an analyst for my shop. Seems like they cost over $600 in 1980 - over $2000 in today's $$$.

[@jrs0007]

HOLY S#!T! $10 shipping for that monster?

[@ObsessionoftheMonth]

I parted out a 1076 but kept the tube, photo multiplier, and flyback.

i have a little emerson color tv that tunes into the picture or audio well but not both

[@tonyp7779]

i have the 1076B. never used it yet.

[@williamsquires3070]

That makes sense as the air breakdown in 10kV/cm, and most (normal) B&W sets used anywhere from 8kV to 12 kV or so, though some sets with extremely small CRT tubes may run lower, at 5-8 kV or so. Another indication of high voltage is several dead insects near the rectifier tube! 🤣 And it’s not a proper resurrection video without a dead insect, spider, or an old rat nest in the set... 😏
