Subject: Re: Polysix 100/120V to 220/240V conversion - Swapping transformer?

From: stalinjohansen@yahoo.com

Measured the AC-voltage coming out from the step-down converter, and it's 127V! (126.8V) That's no good.

Could someone please list the effects on a Polysix (or any synth/audio equipment for that matter) rated for 100V when the incoming voltage is +27V?

I've read that a transformer receiving excessive voltage will overheat, but will components literally die from this? What components are affected by long term use of +27V of excessive voltage?


Also measured the AC-output from the wall socket today. Its 235V. Should i get a 225VA or a 250VA transformer for the Polysix? Can't see that the local store sells any 240VA transformers.. only 225VA and 250VA in that VA-range.
