Hello Kevin, i was wondering if you may be able to help me, i have four c-audio sr606 and 707's in mk1 & mk2 versions, i had Lee Basham repair a 606 mk1 last year but it has died again after only 3 days use, i was wondering if you could email me any info you have on the 606&707 such as specs/data sheets and schematics if you have any.
