Marshall Valvestate 15 Problem
Hello guys recently I bought a used Marshall VS15 (8015), but sometimes the sound fails, and I don't no how it happens. I'm searching for a schematic or a service manual from this amplifier.
Please help me.
Thanks

The valvestate 15 have 2 gain, linked each other, and uses LM1875, but my problem is between , before the tonestack.

Can you talk about that fail? Does it mute the amp?
Sometimes when i'm playing appears a hum and the sounds become saturated, and the bass control has no action when I turn, and the mid pot work like bass pot on/off.
