• Device was repaired in 1999 with 2SC3281/2SA1302. in 2010, the power amplifier was destroyed by connecting defective speakers it was found that the 2SA3201 were fake. Chip size only 1/3 of the 2SC3281. In the 4 643961b8da111c0a15d770a1109a86d4 operating mode, the device was nevertheless stable for years at full load.

• In addition to the transistors, the emitter resistors as well as the 330R, 22R and 2.2R safety resistors were defective. The driver stage was still intact. The lower picture shows the restored power amplifier with the following innovations:
  • new safety resistors 0.5W
  • new emitter resistors MPC725
  • new end transistors MJL4281AG / MJL4302AG
  • Face-milled surface on the heat sink
  • 1.8k, 470R and ZD16V on the left front edge of the boards for higher load capacity rebuilt, cooling vane retrofitted on the 1k8 resistor.
