I have a TenTec Omni VI with the matching Automatic Antenna Coupler and 961
Deluxe power supply. The mod for the continous "on" for the crystal oven
has been done.
I came into the shack one morning to find the PS on but not working and with
the smell of burnt wires. I opened it up to find what appeared to be oil
splashed all over the inside of the cabinet. I also noticed that one of the
circuit board traces had been burned open. I put it in it's box and sent it
off to the only Canadian TenTec dealer.
When I got it back the receiver worked fine but I can only get a maximum of
50 watts out of the tranmitter before the PS shuts down.
I adjusted the current limiting and the voltage with no change to the
output. The tech advised that he repaired the circuit board and replaced 2
diodes. He also said that he ran the PS on a 20A load for 20 minutes
before closing it up. He then suggested I probably had a bad final on the
rig. The rig still puts out full power with a different 20A PS connected.
Any ideas on possible causes/solutions would be appreciated.
