Sunn Solarus lots of hum

[loudthud]

For points B and C the pictures don't show what position the scope's Volts/Div knob is in.

Looks like 5 mV/division to me.

Here are the VOLTS/DIV:

First capacitor after the standby switch - 1 V
Second capacitor (Point A on the schematic) - 0.1 V
Third capacitor (point B on the schematic) - 5 mV
Fourth capacitor ( point C on the schematic) - 5 mV

The probe I am using is x 10.

Did the replacement of the Can fix the hum? Just wondering what the fix was as
I have a similar issue in my amp.
