YES!!! It worked! The replacement belt worked in my S-10! woo hoo!
I know this may seem trival to you 'newer' synth owners out there, but the S-10 was (is) the first (and only) real synth I own.
I case anyone is interested, I was able to find the belt at a local VCR repair shop. If anyone else is looking for a replacement belt for their S-10 (or MKS-100 or similar), let me know.
Also, anyone have a bunch of quick disks they want to part with?
Thanks again,
Bill
