Yes, I tested the tubes after my idiotic mistake. LOL! In my defense, I just bet I'm not the first person to put a tube in the wrong socket! The 7Y4 rectifier tested odd in that it would go high on the scale initially, then back way off into the red or bad. A replacement not any other rectifier that I have tested ever tested quite that way. I am going to try it in the working set I borrowed it from just to note the effect. Also, I jumped a few small value caps as everything is original old waxies. No differences there...

Earlier I hooked up the two sets of antennas as I noted that they had trimmer capacitors on them and I knew that Philcos of this design are notorious for having issues without the antenna hooked up. I was startled by the sound (finally) of some evangelist screaming about the voice of God rushing from my speaker at full volume! So, I am getting somewhere.

Evidently I wired the volume potentiometer up wrong as its full volume all the time. I checked the pot of course and it's within specs. The old one was fully open as I cracked the lid in hope of repairing it, but the carbon was just eaten away at both ends. I created this post mainly to tap this wonderful pool of knowledge about what could or did happen in such a case. Also, having a few nice old Philcos' I thought that others interested in them might chime in with other good info., stories or whatnot.

I'll update as progress continues.....
