Gallien Krueger 400B Preamp schematic needed.

[Westrek]

Looking for the preamp schematic for the GK 400B transistor bass amp. PC board number is 50019C.

GK has the power amp schematics for this unit but not the preaamp.

Thanks!

GK had several variations apparently. That schematic for the 60019A is close enough for my purposes. If anyone has the 50019C drawing, let me know.

Thanks!
