Exactly what I need, thanks!

Thanks a lot for answering. So, it's a kind of Scale for higher octaves. Any specific ranges or frequencies?

Can someone, please, explain what the Hi end pot does on the later Model D:s? What is affected when turning it?
As I understand it, Octave tunes a key, and Scale determines the width of the pitch relative to the keyboard. Calibration seems to work well with those two pots, which makes Hi end a ...

Thaks so much for answering. I've used isopropanol before, but not enough long ago to experience any problems. The keys this time haven't had any springs changed.
Many alcohols are denaturated. What kind would be best?

Hi!
Any ideas on howe to prevent the key contact springs from going to far up the hole of the rubber bus bar? I'm thinking a small drop of glue at the edge of the rubber, or perhaps a small piece of tape across it.

Also, the springs I got from Syntaur are all second hand. Do I need to clean them ...

A model D question:
Which of the gold plated springs are for gate, and which are for pitch, those one or two bars?

I've been told the springs between the double bars are for pitch, but all the problems turning up when I adjust them suggest it's the other way around.

It´s time to do something about the gold plated springs now, after having battled with the bushings the last weekend. Before I do anything stupid and irrevocable, do I remove the circuit board by just pulling the rubber cones up?
I´ve already done one stupid thing, when I changed all the bushings ...

I prefer the monophonic version, without a doubt.
New bushings, along with some contact springs, are on the way.

Took a look at the keybed yesterday, and half of the mentioned C key bushing still stuck to its place. The rest was small bits and pieces. So, new bushings are ordered, but the duophonic behaviour mystery remains.

As far as I remember it, that C sounded constantly, even when other keys were played. Weird and impossible, I suppose, but that went on for just a short while.

Thanks for answering. I'm guessing the bushing got stuck somehow. Owned it since 2001, so it's about time I take proper look in there anyway, perhaps exchange some of the worst springs as well.

Suddenly a tone got stuck on my model D. If I remember correctly, it kept on going simultaneously with tones played. With no idea what to do, I moved the Minimoog a bit, like shaking it sideways very little. The tone stopped, but the upper most C key popped up, about 1/4 inch.
I could, of coarse ...

Thanks a lot for your answer.
Yes, it´s a version 3 model D. Ser. nr. 10XXX something. I´ve had since 2001, I think, a little more than 20 years, and I´ve only opened up the keyboard part once. I messed around with some of the springs, and I´m afraid I didn´t know back then what I was doing.

I´m ...

I have a problem with a few keys, and I was sure it relates to the pitch springs. Typically, the keys trigger and the pitch just runs upwards. Pushing a bit more, the pitch goes where it´s supposed to. I, and I assume many of you as well, then´ll say, clean the springs, or replace them.
The thing ...

Not often I remove the boards on my model D (ser.nr. 11966), but I have to change glide potentiometer, and there isn´t much space to do it with the boards in place. So, while I have two boards removed, should I clean the contacts or anything? If so, what should I use to do that?
