Korg

My condolences on the Korg. Here in the USA they fled and there are no
parts so we have to go through their US parts distributor,
tubesandmore.com, which is a fine company but the parts are in Japan and
they only order when there's a pile, not one at a time. tubesandmore.com,
AKA Antique Radio Supply, Tempe, AZ, is a great company, but getting Korg
parts is measured in Months, not weeks or days.

I service Korg keyboards since the 1980s. Nice stuff, no support.
