[HAM] CV mods

[Dave Bishop]

You're right that all you need is a supply for B+ and a simple circuit to 
attunuate the voltage from the pre-amp's G terminal for a line out.  There 
is a schematic available for a B+ power supply that is a relatively simple 
project, and the line out is even easier.  My experience is that the CV 
pre-amp really benefits from replacing caps and resistors that have drifted 
out of spec, which is about an afternoon's work.  A SS pre-amp would be a 
step backward, in my opinion.
