[ARC5] Transistorized ARC-5 Receiver

[Bill Cromwell]

Hi Roy,

Thanks for that pointer. I have a pair of LMs here and I don't intend to 
convert them either. If I do I will build plug-in modules and unplug but 
not smash the tubes! If a guy who professes to make things can't 
fabricate a "tube base plug" he could always solder the transistors to 
the tube bases just like they did with the resistors, capacitors, and 
inductors.

As for EMPs - if they get to throwing nukes around we will have more 
immediate problems to consume or attention and never mind about playing 
radio. We will soon be gone (if not instantly) and won't need tubes or 
transistors any more. Meanwhile, we should enjoy our gear any way we 
want to.

73,

Bill  KU8H
