[ukvac] tech: Super Monaco GP volume
Hi

When I adjust the volume pot on the amp board, it
doesn't turn the volume down!

I have checked the vr and the resistance does change,
what range should it be?

There don't appear to be any modifications to the
board.

Oddly the coin lamp brightness varies when I vary the
volume pot!.

Any ideas what to look at?

Rob

Sounds like the load the amp is putting on the 12v is causing your coin
lamp to go dim, I take it that it's a 12v lamp ? (some sega stuff is 5v)

I'd check the rest of the amp circuit if I was you.
