Pulled this out of a dumpster.The kid loading the dumpster said it was "perfect" when he threw it in...... Plugged in the loose tubes and powered it up,not bad.
The cabinet is busted to pieces,but it does show signs of life.
I did manage to save a clear case "prison tv" before it got trashed.Small consolation...Now what do I do with this thing???

You could build a real wood cabinet for it.

Definately worth the effort. I bet that is a "low hours" set. Crt looks great. Rare to find those in such condition. Great find!

Yeah, good small delta CRTs are hard to come by. Building a real wood cabinet is a great idea. It would be a "restomod" of sorts, better than new. That's my plan for the top and sides of my Sylvania console, along with a head-to-toe finish change. Why not, the cabinet is rather ratty and the chassis filthy, may as well go all out. That's 1970s luxury man. I guess I've been spoiled by my near-mint maple Electrohome console. :)

Looks like a CTC36, using a low voltage focus CRT.

Get a sleeve of 5GH8's !! The plastic all tube RCA's will keep you busy.
They can look real good but the CRT is critical. Looks nice & brite
with strong snow so this may be a good un. Usually you can change
one low level tube at a time & see slow improvement with each one.
They also all seemed to need the 41.25 & 4.5 traps tweaked.

I built a cabinet for a Sony 27". The original cabinet was SO brittle that every time you moved it, a new crack would develop.
You'll need a scroll saw (to cut the CRT opening). Use all 3/4" plywood and brace everywhere with 2x2's.
It now looks like a commercial monitor.

Vertical/Horizontal Sync issues were always present on these sets - the >180K ohm resistors around the sync, horiz osc and 'GF7 tubes drift high, making the sync range quite narrow. We replaced 180K, 220K, 270K and 330K ohm resistors by the dozens. I wish I still had the RCA Goldenrod on the sync issues - lots of troubleshooting, but 90% of the cures resulted in a resistor change, so we shotgunned the resistors to save the trouble and the call backs...2% metal oxide resistors work fine...

Abe's corollary to Murphy's law: For every RCA with n 5GH8 tubes, n+1 will be bad...:yes:

Nice looking pos. Have you fully inspected all the circuit boards? If one of them cracked when it got chucked... it'll be 'fun' to repair that.

I'm with making a new case. Or... maybe make no case at all. Like just a bare frame to hold the CRT and boards. might look cool. Hey, you could surround it in plexiglass.

I'm thinking a bare "Frankenset" would be cool too..
I would have to fully dismantle the set to repair the cabinet anyway.

I have a few of those clear plastic prison visions. They're an interesting design with a built in DTV converter. :thmbsp:

. How in the world did you get color tv's out of prison? If it has been more than 7 years you can tell the truth without fear of being thrown back in the slammer for taking the tv's we the tax payers own! :banana:

You buy them at garage sales. The prisoner gets released. He saved money
from his prison job to buy it. He gets to keep it. He sells it for $8.

I wondr if any had round color sets? I expect the nut house did. Colors might help occupy their loose thoughts.

I even got them cheaper than that, even free.
Either the prisoner buys it with money earned or the family can buy it. They have to buy them from the prison store and they're marked up high.

Now they have clear LCD TVs for prisons:
