Restoration Update. This radio has a "partial" upgrade to a PM Speaker. The upgrade has a 4inch speaker . The substitue resistors for the original speaker choke did not happen. Instead there is a transformer attached to the bottom in place of the original speaker choke. and 2 30 UF Electrolytics vs the original 20Uf.
Tubes. Of the 6 3 tested good 50, 35, and 7A8 Tube 7B7 test bad. 7C7 50% and 7C6 50%
Question prices quite high on eSlay for the 7B7 but I read the 7A7 is a suitable sub? is thatacurate?
