Looking for GK RB400 Schematic/ Layout

[dobbhill]

Someone gave me an RB400!! The preamp board is disconnected and missing a couple of pots. He told me it works, but I want to make sure I put it back together properly before power-up. I appreciate any shared experience with one of the things. The connection cables from the main (power) board are color coded, but a lot of damage can be done by one wrong move.

Thanks in advance.

Contact G-K.
They are pretty friendly and should be willing to send you a schematic.
G-Ks have a general reputation for being almost bulletproof.
Be sure the connectors from the per board to the main board are tight.
They can loosen up and become intermittent.
