Give me a little bit and I will check on that. Maybe can cough one up somewhere.
The SH-101 malfunctioned or? OK? preventative? If it's malfunctioned, my best guess is it won't tune or stay tuned. There are lots of service sheets and, not any one that I know of that covers everything (unless of course you get all the service sheets that were made!)they typically section the unit off ie. power supply, voicing, signaling. which are you in need for? voicing?
MORPH!
