Hi Guys
I'm looking at buying a studio pre and have heard over the years from guys on the steel guitar forum that a good portion of the preamps have an inherrent hum in the reverb circuit. Our resident amp guru/designer/builder, Brad Sarno felt that a bad reverb tube could not be the culprit, but close proximity of the transformer to the reverb unit could be:
"I wouldn't suspect that the tube would make any difference in the hum. Maybe Boogie addressed the issue at some point. Re-orienting the transformer or the spring pickup coil, or maybe even a mu-metal shield could help it"
Anyway, I thought I would check with the experts here for answers.
thx
bob
