Korg Mono/Poly

Hi everybody:
I need some info about the psu of the mono/poly. Sadly thhe old one
has died I need to know how many volts arrive to the board from the
power supply unit. In the service manual, in the adjustment procedure
I see that there are 3 voltages arriving to the board. +15V -15V +5V,
has anybody the answer to my questio, please. Thanks.

Hello

The transformer delivers 2 x 22,0 Volts AC
After measuring at the two big capacitors I find 25.0 Volts DC at the
large cap, and 26.6 Volts DC at the small cap.

Hope that helps.
