Checked the old threads, and *all* of the links / attachments are long gone. Anyone care to share Barth U211 or U311 Compressor schematics? Even a starting point -- the pinout diagram for the connector, since I'm adapting mine for an ADR Scamp rack running at +/- 28V. I've adapted MXR Auto Phasers and Flangers to this format with a voltage regulator, so hopefully I can do the same here.
