Easy fix and a bargain. The cure is to replace the two 10,000 uF 80v PSU caps. How do I know? Mine had the same fault!steve_1979 said:There's a BK XLS200-DF Mk1 on AVForums for £90 at the moment. It has an intermittent fault but may still be worth considering at that price (the Mk2 version are £315 new) and it seems like there is a way of working around the fault.
