Need help with RCA - Videokarma.org TV - Video

I am working on an RCA KCS-111. The set has been recapped, but the "close" print I have isn't close enough. Does anyone have SAMS 396, folder 3? If so, can you scan the schematic and email it to me?

I have a copy I can scan for you if you don't have one yet. Let me know where you would like it emailed to.

I sent you a PM with my email addy.

My thanks to Charlie for scanning and emailing me the schematic.

I found the problem. When I replaced the lytics, I had miswired the source to the wrong side of the 22K resistor which feeds audio output. I couldn't figure out why there was a dramatic voltage drop after the tubes warmed up.

A stupid error made this set drive me cuckoo.

I corrected my mistake and the set now lives.

Here is the set before restoration:
After pic will be posted to the gallery.

One more time. If this doesn't work go to the gallery.

Here we go again, I hope.

i have the same set and it sits lopsided like yours.
probably missing a rubber pad or such.
gotta recap this one someday.
it is still dump fresh.
one of the computer shop employees went to the dump and brought it back.
