Found a Sylvania SS/Tube hybrid

I almost didn't bring this home. I debated, then I wiped off the dust to get a better look at it. Apart from being dirty, the cabinet appears to be in excellent condition. I think the top is scratch free, which would be amazing! Also it's made from real wood, no chipboard here.

So I dragged the heavy sonofabitch home and made room for it.

I haven't gotten too far into it yet, apart from a quick cleaning, taking a few quick pics, and a powering on test. I'm thinking this could be a winter project for me, if all goes well financially. I'd like to get an idea when this set was made and what issues they commonly have/how reliable they are. This one briefly powers on before the circuit breaker in it trips.

The pictures aren't showing up :(

Guess I am not the ONLY one...who noticed that....

Changed links to imgur. try refreshing...

I tried uploading them here and linking in the post instead of having them as attachments at the bottom. Well it worked for me anyway...

SO...you have a D-12 chassis. I have one too. About 1968-69'ish.

Think it has about 8 or 9 tubes..INCLUDING a shunt reg and HV rect tube.H-out, damper and V-out.osc all tubes too. As is the video out and color amp.

IF, and audio are FULLY SS. Uses one large-TO-66 transistor for a_out, front of chassis, left side.

GREAT catch...I waited WELL over 30 YEARS...to get the one I have now !!

Get us some "nudies" of the chassis...if you can do so.

WE ALL enjoy "chassis porn" here !!

Will do tomorrow, and some better pics. Took these very quickly before wrestling the beast inside.

Any idea what might be causing the internal circuit breaker to trip?

D12 was a good chassis.
Usually tripping breaker is diode in bridge shorted.
If one is bad change all four.
If there is no loud hum then it may be just a weak breaker.
If it breaks after 2 or 3 mn look tward hoz out / hv area.
All of us looking forwards to working on it with you.

Almost the same type of design that my old Zenith solid state 1971 I had ( The cabinet )

Ah, there is a loud hum for the split second that it operates.

I'm not familiar with changing out diodes, apart from knowing that they go in one way and their basic function is to limit current to flowing only one way. Is there a specific rating scale for them like resistors or capacitors? Can I substitute diodes from one of the various TV chassis boards I have lying around?

Put in ecg 125 diodes and you will be FINE. I PROMISE...(in the power supply anyway)

ECG125 is is 1000 V 2.5 amp. will sub most rectifiers BUT
not quite on a few solid state sets. So we used
ECG156 1000 V 3 amp. A little tougher & a little more $$
If thats what it is you could get 10 packs and have spares.
Common problem, we ordered them by the 100.
Next step is see if thats it or something else is dead shorted like
a big filter can.

Cheaper to buy 1N5408 3A, 1000V diodes - 39 cents for one. They are overkill - you could also use 1N5406 or 1N5407...

NTE and ECG parts were just remarked parts - the generic 1N's are usually cheaper.

Since I never want to replace the diodes again, I'll go with the biggest meatiest ones that I can put in there.

BTW: More pics:

I swear the cabinet design of this TV screams "GRANDMA'S TV!" Now my Grandma never owned a set like this, to my knowledge, but had things gone differently this would have not looked at all out of place in her house or apartment. And seeing as she had a good bit of thrifty Scot in her, if this TV was cheaper then a comparable RCA or Zenith at the time, yeah she would have bought it.

I cleaned up the top with a good bit of furniture polish. The top has some light scratches and other small imperfections, but considering it's 45+ years old and looks like original finish, it's in excellent shape! :thmbsp: I doubt anything was directly set on top of this TV. I imagine the person who owned it, I keep thinking it was a grandmother, had various doilies and coasters on it, on top of which sat various knickknacks.

And she would have beat her grandkid's asses if they set anything on top of the bare finish, because she paid good money for that TV, dammit!

Well, before I set anything on top of it I'll put a towel over the top to protect the finish.

These were taken after I spent time and a lot of Q-tips removing a good bit of the dust inside.

And I found out the flyback can be accessed by raising the door on the cage:

And it looks in damn good shape!

Great catch! I stuck it out with similar set recently until I fixed all the issues with it for another VK member. Looking forward to the play by play.

Sylvania color sets have quite a fan club at VK!

I can see why. this chassis looks like it has removable transistors. that and the boards are modular, making tracking down issues easier.

Also good to know that the folks here have experience with sylvanias.
