Hello, I'm in the middle of restoring a R-4C, and the 5 position mode switch S2 has two bad wafers, A and C. Wafer A has phyical damage and C is worn out. I wish to purchase these wafers, or a complete 5 position Mode switch, or an R-4C for parts. If anyone has these parts and wishes to sell them please contact me. 73 David Grossmann 57 Nepaug Road Burlington, CT 06013
