I would check for + & - 40 v on C9.
Then I would check for + 24 on + of C1 and - 24 on - of C2.
Then check +15 on anode of D3 and -15 on cathode of D6.
Warning to new repair people. Voltage over 25 across your heart can stop it. Do not use 2 hands to probe an amplifier with the power on. Use an alligator clip lead on the negative of the DVM. Don't probe around AC input areas, high current AC can melt the probe tip if bridged to case.
Wear no metal on hands wrist or neck. 1 V at high current can burn your flesh to charcoal.
Wear safety glasses. Parts can explode. Solder splashes especially desoldering.
Don't work alone. Don't work distracted by talk or entertainment.
