Hi Folks,

I recently acquired a Philco 37-604. Cosmetically it is in nice shape, it was working although not all that well. This radio was discussed here in an earlier thread regarding its sale and my ultimate purchase on eBay. I have started to disassemble it to undo previous repairs that had been made.
So far my to do list includes;
-Remove electrolytic capacitors that have been tacked on and installed under the chassis, put new ones in the can where they belong
-Rebuild all Bakelite blocks
-Replace wires going to speaker that have been spliced
-Remove fuse holder that is installed next to a tube (tube shield was either not present or removed to make room for the fuse)
-Replace cord with cloth covered cord
-Remove diode installed on socket for 25Z6 GT, and replace the bad tube with a good one
-Replace the 25Z6 tube socket, pin 5 is missing
-Replace reproduction dial
-Repair or replace lamp mask
-Remove the broadcast coil; 1 to repair a broken wire, 2 to anchor the coil to the mounting bracket
-The bias cell has been removed, will install an LR44

So far mostly what I have done is to take photos and notes, and as mentioned above, some disassembly. I scrounged up two tube shields to use in place of the missing ones, machined some bushings for the control shafts, made some checks of chokes and transformers. Removed old electrolytics from their can. Still lots to do, and I suspect my list will grow.

I will replace the tube socket next, and go from there.
