Korg Mono/Poly

Hi,

My Mono' needs help, anyone any idea what the output voltage of the
transformer or voltage accross the smoothing capacitors should be?

Thanks

Mine still has the original label. Check this:

I just measured mine (which is working reasonably well). The output
at the secondary of the transformer is 46.5 Vac. The voltage measured
across the large filter capacitor was 22.4 Vdc. Bear in mind that
these are with a 120 Vac/60 Hz line input voltage, so what you see in
the U.K. may well be different than what I'm seeing in America. I
hope this helps.

Good luck,

Mike

I'm also in Europe but my M/P has exactly the same transformer.
They just put in an additional 2:1 transformer in front of that!

I'm not sure if that was Korg policy or whether I have a US model
that was adapted by someone.

Your MonoPoly seems to be an adapted 110V. Mine is an original european
model and contains only one transformer:

Thanks for the information! Very useful
