For sale are 2 complete Wolverine board kits (4 channels). EF3-4 (V4.0). The kits are identical with the exception that kit 1 has Vishay CPF3 emittor resistors and kit 2 has a set of resistors matched by the supplier of the kits. The Vishays were $100 alone. MJL 4281A/MJL 4312A outputs. Configured for 70V rails and standard input impedance. Boards, heatsinks and quality components supplied by DIYA member M.H. Kit 1 with the Vishays asking $450. Kit 2 asking $350, shipped to the Continental U.S. Paypal preferred. Will ship anywhere for actual cost. I also can supply some nice caps. Thanks for looking.
