BTW....the umbilical diagram in the SM is wrong (big goddam suprise, eh?) I'm not going to try to redraw as Sansui did, but I have made a drawing that shows the umbilical pin number, the wire color, and the pins on the preamp and amp boards they connect to. I may go further and add a second page with a description of each signal...ifn' ya'all want it.
LBPete, thanks for the double-check on the wires. With both this 33000 miswired, and the manual wrong, I didn't have much of a reference.
F'n Sansui.:uzi: :nerd:
