Hi,
I am recapping my old DMagic as everything has leaked and wondered about the design of the main +/- 15V supply with the capacitors C400 and C401, can anyone explain the circuit as it looks like C400 receives voltage agains the capacitor polarity, and they are just normal electrolytic and not BP

These are part of a voltage doubler. What is the input voltage for the supply?
Looks like some of the caps and L3 is not fitted and shorted on the PCB.

The input voltage at CN400 is around 15VAC, I checked a while back the voltage into the regulators was less than the limit of 35V (I recall it was something like + and - 30VDC for each)
L3 is not fitted but C107, C111, C110 are fitted as is R62 and R78
