Cheers for the replies guys , Dean what sort of adaptor have you got , the psu I`ve got is similar to the 1spot and would be perfect for Boss style input jacks not the mini headset style my DOD stuff needs.As I mentioned reversing the polarity may just put the line voltage straight to chassis/earth . I knew in the long run it would have been cheaper to get an ME70. I can see me putting an order in with DVM soon !Originally Posted by DeanEVO_Dude
