OK, I've answered my own query! The Basis board foil that feeds 5.6V to pin 24 on both record boards had opened while on the shelf-this pin sends a signal back through a 1K ohm resistor via pin20 on each record amp board that lets system know it is in place-no record board, no "Ready"! I had replaced C10 on gthe basis board-the foil in question had opened while sitting on the shelf-apparently my removal of the old C10 had weakened the foil just enough to cause it to open later.
