PRS Sonzera Buzz
Long time no see folks, finally getting back into amps after a long layoff due to work and family, anyone here got any experience with the PRS sonzera 50, my nephew snagged one 2nd hand and it has a annoying buzz on the clean channel, tried the usual and gone for known to be good tubes, PCB are a PITA and its not really my thing

Ok with a little and very useful advice from Doug from PRSA, big shout out to him for taking the time , I've now narrowed it down to 120hz interference , changed the earthing a little which has alleviated a little of the issue but still left with a noticeable buzz particularly when the reverb is turned up and down, i'm starting to question the filtering , tried chop sticking the flying leads to no avail, any suggestions?

Update, 6v output on transformer is toasted, just expired after tripping the house electrics, one half of the winding is reading 1.5 volts to chassis, the other 6.3 vots, sort of explains why my filament voltages were all over the place

Does it have a hum balance pot that's shorted?
