Hi,
From a week ago i've noticed that my vh4 slightly hum in channel 3/4.
It is a very suble hum,i hear that only when i roll off the guitar volume and always
after at least 30 minutes of playing.
I put it on stand by..replace power and hum disappers.
Power tubes are 6 months old,
preamp are ruby and thay have 15 days.
I've changed preamp tubes from v1 to v4 with no effort.
Maybe a preamp soket ruined?
