Vox VT-15 low volume, need schematic

[Tech. Tom]

Hello: Does anyone have a schematic for this VT-15? The volume is low and I haven't worked on this unit before.
Thank you.

If you have a preamp problem, I believe it's the same preamp as the VT-30. You can find that schematic with a forum search. I haven't seen a VT-15 schematic, but it's probably a single IC output design and should be relatively simple- maybe a TDA2030 or something of the sort?
