I had a HV short occur in my SB-220 upstream of the glitch resistor. Someone
had installed a fuse in the HV circuit, but it didn't blow. (I haven't looked
to see what rating they used.)
I wouldn't count on a fuse to save the amp.

I have 2 amplifiers, an SB220 and a TL922A,
they both had 10 watt glitch resistors added before I got
them, they have each done their job but self destructed when
they did. I replaced them with 25 watt when it happened. My
question is, one has a 1 amp fuse in series with it. Is that
necessary or is it going to blow needlessly when the glitch
resistor would handle it?
Any opinions?de Dick NY1E
