the solid state
diodes I was using had a much sharper cut-off (reverse current cut-off)
that generated
a little RF hash that interfered with weak signal reception. There were
others that experienced
the same thing. I was not alone. My RME 4350 ran hot, alright, but
propping open the hinged
access door on top helped a lot. Ed, what did others do to stop the
sharp cut-off hash?

Hi, Chief

In case of increased hash with the solid-state rectifier
replacement, I'd add two .01 disc ceramic capacitors
to the 5U4 socket, across pins 4 and 2
and 6 and 2. The capacitors should be rated at 2 KV.
