I'm in the process of rebuilding my R-390. I've been doing some reading on
the net how some people use a resistor and DC blocking cap and feeding the
diode load into an audio amplifier. I've also heard about a modification
that is a more permanent mod that involves changing out tubes and
re-working the audio section. Although I haven't come across that
information yet.

I'm looking for input as to what other people are doing.

Thank you
Bob/N1XBM
