[Amps] Glitch resistor + fuse?

[Paul Kraemer]

The lo ohm resistor Drake used as a fuse in the hv lead works very well.
Harbach has them
I have ended up putting one in every amp I have followed by conventional 
glitch protection.

Hello Dick,

Keep both in.

While the resister does the most protection, I HAVE seen resisters that have
shorted. This is rare as most time they either open or increase in value,
but shorting can and does happen at rare times. This is something that is
not often talked about. It would be then that you will be glad that you did
NOT remove the fuse. I have found that the more time you spend in
troubleshooting, the more events you will see. I have been professionally
troubleshooting since 1971 and seen some darn funny things. Hope this helps.

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
