This radio was a real challenge. The owner
wanted the radio fixed, but also wanted the electromagnetic speaker
replaced with a PM type. The speaker itself was heavily damaged and the
radio appeared to be water soaked. (The owner said it was not). See
Figure 1.
The Electrolytics had already, many moons ago,
been replaced with large under chassis caps. The line cord
was shot. All the remaining capacitors looked to be 65+ years of age -
little time bombs waiting to go off. The power transformer appeared to
be ok as did the rotary switch for band changes.
Ultimately two tubes had to be replaced - a 6Q7
and a 6F6.
