Pulling hair over Apex 7A!
#14

Icon_smile Icon_smile Icon_smile WELL NOW....

In the process of taking a bunch more voltages in order to get more troubleshooting help, I discovered something that I had missed: the 3200 ohm section of the OTHER Candohm was open! I had not caught this previously, since there was voltage at that point, and since there were no voltages for several points in the power supply train, I just assumed it must be the right voltage. It was ~35 volts.

I decided that I would try to figure out what was supposed to be at that point, and so took a reading on that section of the Candohm. It measured into the 100's of thousands of ohms. AHA! I went and got a 3300 ohm 3 watt resistor and subbed it across. I fired up the radio and VOILA! It's a radio! Great AGC action, even better gain than before. In fact, it's pretty amazing in the stations it can receive now that it's working and hooked up to my longwire.

I want to thank you all for the help you've given me on this set. I'm very happy that I've been able to make it work with all it's original values back in place. Icon_smile Now I just need to find a nice matching set of knobs and finish repairing the cabinet.
