B15N now grounded, so what else redundant?

[mynamehere]

My '66 Ampeg B15N now has a 3-prong power cord, do I need:
1 a ground switch
2 a hum balancer
3 a 'death' cap
I ask 'cos I'm also getting a 'pop' coming out of standby

[Enzo]

1. no
2. yes
3. no

Popping on standby switch has nothing to do with mains wiring. It is also quite normal on many many amps.

Thank you.
I'll disconnect the redundant parts - do you think I should install some kind of 'bleeder' cap (or whatever you call it) to the switch to stop the popping?

[Enzo]

I personally don;t worry about switch pops. If they really bug you, try a cap across the switch. A .01uf or maybe .047uf film cap at 1000v rating should do fine.

Thanks again
