Sounds like your power supply's pass transistors may be shorted. Adjusting
something that is broken is usually a mistake.

Subject: [TenTec] 961 power supply adjustments
|
| Over the last few months, my 961 power supply has become more finicky, and
| now shuts down whenever I turn on my Omni VI. I switched the Omni VI to a
| backup supply and it seems to be operating normally.
|
| I have no schematic or owner's manual, so I am in the dark. I note that
| there are two (2) potentiometers in the supply. I assume one is for
voltage
| and the other is to adjust the overcurrent trip point. I suspect that the
| overcurrent trip may be too sensitive.
|
| Does anyone have any experience adjusting this, or any advice as to where
to
| begin looking for the problem?
|
| Thanks and 73 to all,
|
