If it turns out to be a bad diode, and I cant gind a germanium, can I use a
regular power supply type diode to replace it? Date: Fri, 4 May 2012 07:55:45

Check the germanium diode that provides the voltage for the "forward" or, in
this case, the power output, indication. There are 2-diodes, 1 for forward and
1 for reverse (SWR position). It sounds like the forward diode is bad. Very
common!
Also, clean the meter switch. Glen, K9STH

I have a Heath SB 200 amp that is working fine with one exception. The meter
is not functioning in the power out position.It reads fine for high voltage,
grid, and SWR functions, just not for power output. I have to use an external
wattmeter to tuneupand check power output. I thought it might be just my amp
until the other day when I was at a ham friends of mine, and he told me he had
the same problemwith his SB 200. Anyone else had this problem and know what to
do to fix it?
