Ashly SC-50 Black Face Schematics?

[user 40373]

Does anyone have a readable scan of the Ashly SC-50 schematics (black face model). I picked one up recently and plan on doing a complete rebuild to clean it up, because they are a little noisy.

Ashly was kind enough to e-mail me a schematic, I'm not sure what revision it is.

According to Ashly, this is the only schematic in their archives but it should be pretty close no matter which revision you have.

Looking for a schematic for an early SC-50 compressor - does anyone have it?

Here you go!


btw... I love that comp! I have SC-55 (same but dual channel) - the best thing on electric guitars!

Had a very helpful - and very prompt - reply from Ashly to my email. The schematic above is for the early version of the SC-50 which uses matched pairs of transistors in a metal can. This is the type I have. The later version uses a dbx chip

According to Jim at Ashly: "If you do have the original version SC-50 with the matched dual can transistor VCA, it is important that no substitutions be made concerning the IC chips. The circuit was designed around a special mode of operation only available in the 301 IC"

Thanks for the help, shot & Jim

Is there any chance to get the schematics for the SC-50 again?

Here's an Ashley SC50 schematic I have.
