[Milsurplus] PRC-74 questions

[Robert Nickels]

I've been able to get my newly-acquired PRC-74 working on receive at 
least, after replacing a bad "varistor" in the 9 volt regulator 
circuit.  Anyone know what these parts are, exactly?  With a nominal 
resistance of 300 ohms, they're not what I think of when I think 
varistor (i.e. MOV).

If anyone has experience working on these radios I have a couple of 
questions related to the mechanical linkage between the Mhz selector and 
RF unit.  The front panel is pretty cramped and complicated, and I'd 
like to make sure I'm on the right track.

Also - is there any info on LSB conversion?  It seems that this was done 
to my unit.

Thanks and 73,
