Hi Mark,
I had one of these a while back....nice amp! If you short pin 9
(Orange wire) and pin 2 (White/Black wire) you can energize the p/s, if it
has the cover attached. The power supply has its own saftey interlock. BE
CAREFUL!
If the problem is not in the P/S, remove the 3CX800's and try to
power up the amp (With the cover ON!). If that doesn't blow fuses, try one
tube at a time and see what happens.
If you're not comfortable working around high voltage, DON'T
MESS WITH IT, let someone with more experience check it out.

Subject: [Amps] Ten Tec Titan 425 Fuses Blew
Both the 20 amp fast blow 240v fuses just blew in my Ten Titan 425 this
evening while I was keying about 1200 watts on 160m. I am told that I can
get Microwave 20 amp fuses from Home Depot.
If these new fuses blow and I need to do some fault finding, can I power
up the psu via the rf deck with the HV cable disconnected at the psu end
as I would want to be able to take the rf deck out of the circuit.
Any other fault finding tips would be appreciated.
