RCA TC-127 restoration nearly complete!!

[Tubejunke]

I decided to make a new thread concerning this project. The original thread was named for my original power transformer problems.

In short everything went well with this set. I can rest and play the set with confidence as the ENTIRE power supply was replaced. Also I replaced ALL electrolytic capacitors and 95% of the paper caps. The rest are coming. The remaining caps check OK but I'm still replacing them.

Heres where I stand. The set powers up and dispalys a good picture with low audio output. After about 2 minutes the horizontal lock kind of intermitently comes and goes. When it comes in it is not real stable and may display some horizontal roll and then lock. The adjustment on the back is cranked as far as it can go and so is the hold control. Obviously some component has changed value. I hope it is that mean, ugly, 1000 volt black beauty paper cap that remains. Now the sound problem is a bit more of a mystery as ALL of the caps in that section are new. I found a 150 ohm resistor that had doubled in value. A small improvement maybe but still no cigar. Very low volume..

If I can lick these last small issues I will have one beautiful old RCA to watch for years to come.

I can get more enjoyment out of watching this kind of set than one of these crazy wide/flat things at Wa-Fart that everyone is so worried about.

Kind of A** backward to people I know. Thats the fun of it!
