Here are mods done to a Jolida FX10. Forgot to take pics of the Power board but it has upgraded JJ caps and IXYS and Cree hexfred diodes for the B+ and microcontroller power. Baked some pennies and taped them to some wire. The pennies went on top of the B+ caps and the other end of the wire taped to the chassis ground.
The main board was upgraded with new bias caps (nichicon kz and solen mkp), wirewound resistors (mills) for the feedback path, new coupling caps (solen mkp), new caps for the volume knob motor (rel-cap film and foil and vishay-roderstein mkp), and a new cap for the microcontroller (ROHM film and foil bled with 4 series vishay-dale metal film).
The B+ clamp capacitors and bleeder resistors did not fit in the chassis and are mounted externally (solen mkp and kiwame carbon film and MIAL film and foil).
EDIT: sounds really good except for the constant sound of a garage opening. Or a dryer. I think there might be too many parts now...which ones are the question
