BVARC,
I am looking for suggestions for a power supply repair person/company here
in Houston, if they exist. The needed repair is a Ten-Tec Model 962 power
supply that works with my Ten-Tec Omni VI Plus. Thank you for your help and
any suggestions you may have.

Gayle...you asked aboutthe PS.
Specs -
Current out -- continuous 22 Amps at 13.8 Vdc
Front Panel Adjustable Voltage (9-15 Vdc)
22A continuous is plenty for 100 W xcvr.
Adjust the DC Volt knob for a reading of 13.8V on the meter.
Maybe you are meassuring in the AM mode...bet your rig goes to 50

You need to measure the voltage as I indicated with the rig in CW mode into
an antenna or whatever you used before when you measured the power output.
Now a cheap but accurate digital volt-ohm meter will cost as little as $10.

Measure the actual under load (100 W. CW) voltage
at the back of the FT-920. Faulty inline fuse holders
or connectors, and wiring losses can cost you 1/2 v. or
more. You need a full 13.5 to 13.8 VDC at the back.
Since power to a R Ohm load is V*V/R, a relative power
