JCX-2600KR repair both channels pumping

Low frequency oscillation on both outputs:

Have a look at the voltage regulator,
page 24 of the pdf manual (is "23" in the original).

Check caps, especially C 921, 922 ,
check resistors R 920, 921, 922, 923 ,
Q 902 gets hot, added a small heat sink ,
Q 902 and R 920 heat up C 921 ,
C 921 had to be replaced ,
check solder joints on hot components.
Done.

Sadly the regulator board is hard to get out.

Remove C "Capacitor" on the "power switch PCB" if it is the fire prone
RIFA from Sweden. No replacement required.
