I finally pulled the trigger on one of these https://www.brownbox.rocks/products
Does anyone here use them ? I figure that amps designed 60 years ago might need them ...I use amps from the 60 and 70s when playing surf at some sketchy locations and power supplies ( generators , industrial rehearsal spots ) and sometimes the amps sound great , sometimes less than great .
.Id just like to know that Im getting good clean mains power because Im certain that's rare coming right out of the wall .
