I'd first suspect the cap, but polystyrene's are pretty long-lived. The 4051 and TL082 should be considered as well. I'm a bit surprised though that you don't drain the "good" one when testing, it doesn't take much to make it fall off, even with a good, high-impedance scope. One thing you could do h...

You need all the original boards and a working synthesizer for the Kenton system to work, it piggybacks onto the key assigner. Without the KAS and SH cards, it's useless. If all the Yamaha chips are on the voice cards, I'd say you got a good deal. I certainly would have snatched it up for $600. It's...

So, I finally got a CS-80 a couple of years ago with it's excellent PAT implementation. I really enjoy using it in many ways. My favorite is accentuate the main note of a melody while playing the supporting chord structure. The synth really shines when playing this way. It takes a lot of practice an...

Glad you found it useful!

Be careful not to stretch the aftertouch membranes.

Be careful not to bend the conductive strips. Don't touch them with bare hands after polishing.

A good cleaning will restore the aftertouch 100%, unlike the JX-10. It's a bit tricky, just go slow.

Haven't had trouble locating the OB-6 keyboard, the desktops are a little scarcer. Haven't looked for anything else...

I'm in the same boat, need an ig00158 WSC chip.

Please PM me if you have one for sale.

WTT:

Have: Rebuilt and refinished, minty 100% working Rhodes Chroma with aftertouch and CC+

Want: Minty CS-60 with lid and legs

USA. Have some ideas on shipping depending on location.

Well, yes, in a sense. The digital info (which will be essentially the same on all computers) is converted into analog voltage by the sound card, so all will sound different. These days however, they are probably all so very close to each other in performance (at least with the lower end units) that...

I thought the price for a Jupiter-8 was nuts when people were asking $4500 - 5000. Now it's pushed into the bizarre, rarefied world of 5-figures, at least asking price, anyway...

The LAMM Memorymoog is even worse.

An MKS-70 is welded into my rack for the reasons above.

Is anyone using the Vecoven microprocessor modification? I have a JX-10 I bought with the thought of doing the mod, but never got around to it. Curious about the snappier envelopes and extra LFO, would be nice to hear some examples.

MIDI Solutions in Canada is the best starting point. MIDI merge boxes that do what they're supposed to do.

Hi Kevin. No, I never got a bite on the above post.

Good idea to post on the Yamaha CS FB site.
