Steve:
Do the fuses blow when the HV cable is disconnected from the back of the RF
deck? That would isolate the problem either to the power supply or the RF
deck. If you have already checked the transformer, diodes and filter caps,
then check the "dead man" shorting bars in the power supply and RF deck as
well as the HV connectors. Take a look at the board in the RF deck with the
meter dropping resistors...I had a capacitor there short to the chassis once
in mine, but it made a loud bang and some smoke.

Subject: [TenTec] Titan 425 Amp
Hello all,
I'm working on a Ten Tec 425 amp that blows both 20 amp line fuses and the
240
volt outlet breaker. I've gone through the power supply in detail,
inclusive of
replacing the transformer. I've noticed that it will blow both line fuses
and
the outlet breaker once the interlock switch on the back of the supply
that
feeds the orange wire to the amp is engaged. But everything I check on
that
orange line seems to check OK.
Any advice would be greatly appreciated.
Thanks,
Steve
