Vintage Synth Repair

Thanks for that pinout info Daniel.

Oddly the 'limited' service manual psu overlay shows pins 7 and 8 from the
PSU as being linked on one pad at the PSU end.

Emailing me pages from your version (PSU end and desination ends) of the DC
would help, but the whole manual would be even better !  If not email, then
one of the 'benevolent' online manual repositories would be an idea. But NOT
one of the ones that charges money to access.

cheers
