[RFI] Dimmer control

[Gary Smith]

Hello folks,

I just picked up a nice guitar amp, one of 
the better made ones (Mesa Boogie) and 
running it at night I found I was getting 
buzz that mostly all goes away when I 
touch the strings. Trying to track it 
down, there was no hum with the 1/4:" 
instrument plug removed from the amp. I 
soon found much of the noise to be coming 
from the lights on a dimmer switch. 

With the lights out there's still some hum 
that goes away when I touch the strings, 
but that's for me to the track down next. 
For right now, I would appreciate knowing 
what wall switch dimmers I might get that 
are known to be acceptable?

This particular one is many years old, one 
of the ones you push in to turn on/off and 
rotate the same knob to change the 
lighting intensity. It fits in a single 
switch wall socket. Though it's not 
getting into my radio that I can tell, it 
does need to go.

Any suggestions of a known well made & 
friendly dimmer?

Thanks & 73,

Gary
