Hiwatt/MaxWatt B100 15 Bass Amp. - Schematic


New Member
Can someone help me ?
I need the schematic diagram of the Hiwatt / MaxWatt Bass Amplifier Mod. B100 15, or just the GA75-B power board.
Is it possible for someone to provide me?
I appreciate the attention.

Assuming that's a valve amp?, then it's simple enough not to need a schematic - and VERY often they changed throughout production, so any schematics out there often aren't accurate anyway.

Funnily enough, HiWatt aren't that far from me, and a friend applied for a job there as a service engineer - unfortunately he didn't get it.

What's the fault with the amp?.
