[Milsurplus] "Correct" fuses for BC-342??

Phil,

The correct fuses are 10 amp 25 or 32 volt.  Hot filament current is about 
1.3 amps.  At turn-on, probably twice that.  I'd check C78 and C79 and the 
filament wiring.  Remember that if the RA-20 is connected to the radio, C79 will 
show low resistance to ground through the filament winding (center tap is 
grounded).

The BC-312 and BC-342 both use the same front panel fuses.  In the BC-312, 
the DM-21 also runs off of the filament fuse, which is why it is labeled 
DYN-FIL.
