[Amps] L4-B

[Edwin Karl]

Just be very careful with the power resistors used in the bias cutoff/ 
bleeder
They are mounted on long screws that run through the center of the 
resistor. In
repairing an amplifier for a buddy, I had the resistors short through the
porcelain of the resistor.

The fix is use good 3m glass tape to insulate the screw, and enough on
the ends to insure centering the resistors. Unlike electrical tape, 
glass tape
is rated at 240 degrees and will withstand the high heat. Make sure to 
reinstall
the mica insulators.


Good Luck!
We're all counting on you ...
