This is an expansion on a previous post in the "testing this forum" category,
I submit this here because it is synth related and there appears to be nowhere else to post it.
That being stated...I am referring to the mysterious SM-75 and the little sibling PM-30. Both are vintage 1985.
http://www.korgforums.com/support/brochure/SM-75,PM-30_Brochure.pdf
I serendipitously have come across one of each.
I like them both a lot...I use the SM-75 on gigs regularly.
It is very sturdy and dependable and yields a solid sound through a simple design with quality components.
Searching for another has brought crickets, although I have recently won a bid on a SM-75 on a Japanese site. Waiting for delivery details to transpire.
Japanese AC is 100V. I was looking for a schematic to see if I could tap the transformer to get it to accept 120VAC, but crickets there also.
I will probably end up getting a step-down transformer.
I did talk to two techs who said they came across these back in the day. They said the amp was a design they could work on without reference documentation!
So I am reaching out to see if anyone has or has had or has seen any of these? _________________ orig CX-3 (sold) M1 Plus 1, Wavestation EX, TR-76, MS2000R, X-50
