Help With SIGMA XR3000D HF Amp?

[DavidC]

I have a SIGMA XR3000D 160-10m dual 3-500z Amp.

A friend is working on it trying to chase a couple of
bugs -- he has asked for any suggested mods and
warnings about likely weak spots while he is in there
that he may compensate for (e.g. underrated diodes,
caps, switches, faulty high-swr circuitry, etc.).

Thanks in advance for any assistance ... sure would like
to get this thing on line soon!

73,
