A second option exists. When you first power up the 922 don't panic
over the current being drawn and jump to turn it off. Wait for 10 to
15 seconds to see if the filament heating and resultant thermal
expansion will eliminate the short for you.


Very dangerous with the TL-922. Due to Kenwood design fault, the 80V
service voltage gets shorted to ground when a grid-to-filaments occurs.
After a short while the service transformer (T2) will be permantly damaged.

Thanks Tony for that information. I was unaware of that design in the 922. I run
Ameritron stuff.

But, poping the fuze is still worth a try. You do have to remove the 3-500 from
the amplifier to pop the fuze.
