Dual rectifier hum
Just swapped out the tubes on my rev G Dual Rectifier and noticed a bit of hum coming through the cabinet. Hum is present with nothing in the input and volume all the way down. I turned standby back on and then noticed I can also hear the hum (albeit faintly) coming from the chasis near where the power chord plugs in.
Hum is most noticable on the red channel but you can hear it on the orange channel as well, but quieter.
Ive already put the old tubes back in, so its not the tubes. New tubes were a DR set from Eurotubes.
Is this normal? Ive been told its normal on a lot of higher wattage amps to hear electrical buzzing/humming come from the electronics but ive also been reading it could be a filter cap. Any thoughts or suggestions?
Its not an extremely loud hum or buzz. Its kind of like the sound you hear when you walk past a transformer on the street or something.
Any help would be appreciated.
