6TPZ and 5TPO Radio Help
#12

Thank you morzh. I sincerely appreciate the advice. That's why I'm here. I am ready and eager to learn. I have a lot of experience in electronics in general (mostly pc circuit boards). I have been successful in tube radios and transmitters, but maybe i've just been lucky. I've been tracing the schematic out. Everything I replaced is correct (quadruple checked). I used the values that are listed, which happily matched the ones I replaced. I removed and checked the capacitors again, then replaced them. I have not checked all of the transistors. Everything was doing ok, just no sound. Voltage and amps were stable. Then, (now both radios) only want to draw 5-7 volts. So, I'm having a lot of trouble tracing out any voltage drops. While trying to measure voltage I scraped my hand across a few solder points and could hear scratching in the speaker. I really was trying to be methodical. Clearly I missed something big. Point 18 was 12.6v and point 18 was 10v. This was good for a while. I was testing the other points and then things started fluctuating with the voltage. I will try testing the transistors now. Thanks again.
