Archive of the former Yahoo!Groups mailing list: MOTM

OK, I've been informed that the synth-diy list has been down a couple
days. Perhaps one of the MOTM folks that also have an MS-20 can help with
my question:

I've decided to rewire the AC line side of my MS-20 to use 115VAC as
opposed to its stock 230VAC (unit was originally in Europe). Looking at
the transformer, I notice two extra, unused primary-tap wires that have
been sealed up in heatshrink.

Now, my other Korg gear uses this same style of primary taps to select
the input voltage, so I figured this is also the case for the MS-20. My
question is, which two wire-colors are used for 115VAC?

I could measure the winding resistance for each tap, but then I'd have
to take the entire cabinet apart whereas I'm trying to get this done with
just the right-side end cap removed. Thought I'd ask to see if someone
out there 1) has already done this and can tell me which wire colors, or
2) can take the right-side end cap off their 115V MS-20, look at the
transformer and tell me what the connected wire colors are. The service
manual doesn't show this.
