If is faulty will take it to a shop about an hour away in hopes of repair. Would I need specific parts from Johnson or should they be able to fix it by sourcing parts?
and when you switch it back to the nohummer it goes away(?) I assume...
If that is the case, then it is the amp.
Especially if no matter where it goes, the hum goes with.
Is that what that 85db 60hz peak was in your system?
If it is just a few components they "might" be able to swap it for like-values, for major stuff Johnson will have to supply all the parts.
