Well here's where I stand tonight. I checked pin 5 of the 6a8 and get -1.3 VDC. I then checked all of the cathodes and each reads zero volts.
So I decided it's time to get out the signal generator and try to inject a signal. I was getting a signal to pass through the entire audio output section, moved over to the RF section and was poking around a bit. All at once it started to play! I was getting stations throughout the dial, albeit stronger / louder on the lower end of the dial. So, after letting it play a while I decided to upgrade a few of the tubes, as I had some that were Philco brand I wanted to use for originality. I replaced the 6K5, tried it, and it played fine. Moved over to the 6J5, replaced it, and, once again it reverted back to its old dead ways. So I put the original tube back in and STILL nothing!
I had it, and lost it
But, this tells me I have a bad connection or bad solder joint somewhere, and that's what I will concentrate on tomorrow.
So the status for tonight is close, but no cigar.
