As you can see, I went in and removed nearly everything from the IF amp through the audio outputs. I think it will be easier this way. It has to be rewired anyway due to the dried-out, nasty rubber-covered wires.
Arran, I was able to remove everything from the other tube sockets in this area which I want to keep without any other contacts breaking or otherwise coming off from heat. I found that it was easier to remove wiring from contacts when I had a tube plugged into the socket I wanted to keep.
So...as it looks right now, I will only have to replace the 6H6G (2nd detector) and the two 6F6G (audio output) sockets. I'm hoping I can save the det-osc, rectifier, and tuning light tube sockets as well. We shall see. But since I've completely stripped this area, I will concentrate on it first.
Ron;
I will have to keep that trick in mind with regard to octal sockets in Philco sets from that era, but with Electrohome sets it would not help, the terminals have a habit of snapping off right at the slots where they slip between the layers of phenolic. For whatever reason the manufacturer of the octal wafer sockets used in Electrohome sets decided it would be a great idea to stamp a 1/16'' knotch in each edge of a 1/4 inch terminal leaving a weak spot in the brass where it goes between the phenolic, stupid, stupid, stupid. Philco must have used some sort of fixture to prevent the contacts from being torn out of the socket of these gold socket, that or the material was much more resilient when new.
