[TenTec] Titan 425 Amp

[Ron Castro]

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.
