I am starting the restoration of a 37-2670 (Export Model) set. This is a very complex 11-tube set with 5 bands including long wave. But unfortunately it uses the famous 37 RF subchassis. This one is especially packed - no way to get to the bypass caps. I have read all the info I could find on philcoradio.com and the philco repair bench.
It looks like all the wires going to the subchassis can be unsoldered from the MAIN chassis area - they all appear to go to tie points. It then APPEARS that the RF chassis can be removed. Looks like the sides can be removed, which would allow somewhat easier access. I have no done this before.
Does anyone have any previous experience they can share, or point me to other information?
The only major defect I have found so far is the output transformer (open) and of course the Candohm. At least no one has ripped out the bakelite blocks, and the power transformer, choke, speaker field, and even the shadow meter coil are OK.
Thanks for any help,
Dave
