Discussion about the Korg PolySix synthesizer

I use 50VA 2 x 15V toroids from Vigortronix.

Easily enough overhead to work at 220V. If that makes you nervous, 
particularly if your line voltage frequently falls below 220V, then use 
a 2 x 18V.

A 2 x 24V transformer will work but will cause the power supply to 
generate a lot of heat which will need to be dissipated by the rear panel.

Also, virtually every Polysix and Mono/poly I have seen has a blown 
'spark killer' capacitor on the mains in board. Remove it and don't 
bother replacing it.
