KPA100 question

[Mark Flavin]

I know its possible but just to verify could the d16 and 17 chem ok and be  
bad?  Im getting high power and current which from the archives suggests  
them but they chk about 380 ohms.  The q1 and q2 are ok.  Works fine below  
10 watts.  Thanks

Mark,

The real answer is YES.

Measure your actual power when the power request is set to 5 watts - if
it is really 12 watts or more, then that is an indication that the power
control is not working, and the KPA100 wattmeter diodes are the first
suspects.

380 ohms is much lower than normal, but that depends a lot on your
ohmmeter.  They should measure low in one direction (normally about 3K)
and quite high (about 43k) in the other direction.
