If you look at the schematic or the jack board (Jack 1 Unit - page 68) in the service manual, pin 4 of the ACC-1 and ACC-2 are connected only to the Exciter 1/Exciter 1&2 switch. In the single exciter position the two jacks are connected together, in the dual exciter position the two jacks are disconnected. Neither the "stepped voltage" nor the 8V reference on pin 1 appear to be used anywhere else in the PW-1. It would be difficult for the stepped voltage to switch bands in the PW-1 if it is not connected! The only purpose of the "stepped voltage" connection appears to be as a "feed through" when connecting another Icom accessory to ACC-2. 73, ...
