National NC-120 manual
I am restoring a National NC-120 receiver. I understand this type was
used by the US Navy during World War 2. I need a repair manual with
test information such as tube socket voltages and a schematic with
component values. One similar to the ones I have for my BC-348 R and
Bendix RA-1B that has pictorial drawings of component placement and
arrangement of wiring would be great. Also any advice from anyone with
experience with this model will be appreciated. So far I have found the
power supply voltage to be about 220 DC and all the tubes test OK, but
some of the socket voltages seem wrong to me but I am not a radio tech.
The radio was working and just faded out.
Thanks
