I restored this power amplifier with:
- all new diodes
- all new resistors (Takman REX with some Shinkoh, Ohmite, Amtrans, and Mills)
- almost all new capacitors (highlights include Audio Note KAISEI, Mundorf, and for the film caps PPS film...to copy what the high-end Yamaha is using)
- 4 out of the 5 bridge rectifiers have been upgraded with SiC diodes with 0ms delays
- RCA input jacks added
- transistor sockets cleaned and transistors reinstalled with SIL pads in place of paste
- some other odds n ends transistors in the power supply.
