Next Project - 37-116
#20

First power-up: mostly successful!  Radio started playing at about 60 VAC.  Stations all across the dial at 70 volts.  Works good at full voltage.  Magnetic tunig works though needs alignment. Two problems show up:

1.  Looks like I was not lucky on my Police band  oscillator coil rewind. Entire band dead except on the extreme high end.  I get one station.  I'll play with that a while before I try a rewind.

2.  Audio hum that goes away only when the hum balance control is to one extreme.  At that point I get smoke out of the WW balance pot.  I'll have to check my wiring.

Better to work on individual problems rather than a completely dead unit!!
