Hello,
 
I have a 962 Power Supply Im using with my Omni 6+. I recently had the 
rectifier fail in it. I replaced the rectifier, pass transistors and all filter 
caps in the unit.
The supply operates fine however I noticed yesterday when I accidently keyed 
the rig into a high swr the supply didnt trip and shut down.
 
I was under the impression the supply has a circuit breaker, however reading 
through the description the supply has an electronic current limiter with a 
factory set threshold of 22 amps.
 
My question is since I've replaced major components of the supply and likely 
affected the overcurrent trip settings how do I adjust the electronic current 
limiting to the proper value?
 
I have 2 pots in the supply R24 100 OHM which is off the B+ rail and goes 
through a resistor to to pass transistor Q8 and R30 1K which is between the B+ 
and B- rail and the wiper going to the small IC which I assume is the regualtor.
 
If someone has done this before or has any info on the adjustment procedure any 
information would be greatly appreciated.
 
73,
George K2JYL
