Hey All, 70's rca color tv, worth the effort?

[zeno]

Its the last delta tube set & the last modular RCA. I saw
very few of them. We did tons of RCA so that means they are
rare or very reliable or both.

The set uses an SCR for a regulator & can be a bitch to fix requiring
all the equipment ( meter, scope, variac, DC power supply ) also
knowledge & patience.
The power supply, horz osc & HV all have to be working or you get
"dead set". There is also a one chance kick start for the horz osc.
to spice things up !

If you look at it & dont hear the quick degauss hum at cold turn on
it may be just the main fuse. ( 7 A fast blow)

Well i don't like weird power supply circuits and it sounds like a bit of work just to find out if the crt is worn out. i haven't justified the expense of a crt test/rejuvenator yet,so i think i'm going to pass on this one. Thanks everyone! it is in Hendersonville tn about 10 miles northeast of Nashville if anyone else is interested.

Honestly I would bet if given enough time the owner may decide to just give it away for free or dang near it. I live near Knoxville and know from experience that the Tv market in Tennessee isn't the best.. There's plenty of vintage TV's on the Knoxville craigslist and a couple similar RCA sets.

Anyways, good luck. It's nice to see someone in this area who also messes with the stuff.
