CTC10 Finally a failure

yes you will have no color without the neon lamps. steve

Thank you Steve after looking at the circuit I believe your right. Also lowers the brightness too without them. Anyone know where I can get the Thermistor 79 ohms cold. I'm working without it but would feel better with one in there. Don't like to surge that 55 year old transformer. Thanks everyone for the input.

I got a free CTC-10C set in 1975 that had a broken CYP22 kine. I had an FBP22 in my garage that I installed in this set. It works.

Other than a few tubes, the ONLY problem I've seen with my 10 is bad soldering between the chassis ground stakes and the PC boards. The horizontal oscillator board could be tapped with a pencil eraser and the screen image would lose horizontal lock.

I also replaced those neon lamps when one of them broke a lead.

My set has seen no tube replacements since 1979, and is still running just fine on its OEM capacitors.

Don't trust those caps. I tested mine almost 3 years ago with my ESR meter. All checked great. But now that I play it daily they died. Changed them all. You should do the same. Also I found don't trust the meter on your variac. Boy does that make problems you've never seen. Was set at 120 and it was 115. Plays great when you crank it up. Lesson learned

After a few weeks of waiting for parts and time to do the job my set is back among the living color. Must admit it turned out great. Thanks for all the input everyone.

It looks great, Tom. I'm sure it feels really good to have your baby back on line
