Plan B M15 sine wave adjustment mod

Author Plan B M15 sine wave adjustment mod
Tim Stinchcombe
I've spent the last few evenings carving-up my M15, to see if I could make the sine wave adjustment process any easier. I succeeded, and have written up a web page here:
http://www.timstinchcombe.co.uk/synth/m15_mod/m15_mod.html
However the mod is pretty complex, and because of access problems on an ordinary M15 (I've modified mine to be able to pull it apart at will), it doesn't have much to recommend it, but it might be of academic interest to some.

Nice work Tim,

Too much for me to bother with but if your offering a service?

Very interesting read, Tim. Thanks for going through the trouble and then typing it up. Far more of a PITA than I'm willing to do right now, that's for certain.

I'm not totally averse to the idea - I'll see if I can gauge from my module how easy or otherwise it will be to get at stuff on an un-hacked-around-module, and get back to you...

I'm also of a mind to see if I can replicate the bleed-through from noise on the power rails, and ameliorate that (if I'm right about the cause - a way too small cap brought across from the original Buchla schematics, which looks like it could do with beefing up). Need to see how badly I can load a Doepfer G6 case...

Again, thanks Tim.

I love my M15 despite it's faults (regard them as features now) and would love another. Keeping them up and running has always been at the back of my mind.

Cheers
