My MXR-130 has been collecting dust in the attic for 10 years and I finally took over some space in the basement for cranking the jams. I'm having some problems with it and am only using the outputs to drivie a pair of Kenwood KL777DX speakers. I happened upon this site in search of parts.
Well, off to the "repair/help" forum.
