Hi Rick.
I just find one of your old treads about Optonica Amps. I need all documentation cause I just purchased vintage Amplifier "Sharp Optonica SM-3636" and I would like to restaurate front panel. Unfortenately my unit don't have original knobs and I really would like to bring back its original look. SM-3636 knobs have those unusual shape so I will appriciate any documentation (manual, service, etc.). Maybe I will be so lucky to find someone to build it from peace of aluminum, but I need exact measures. It is really rare peace of gear and I couldn't find any documentation.
I'll appriciate any help.
Kind regards,
Nenad Staletic
