Re: UK700 PSU running at 18.1 volts

and ..what mains voltage is it rated for and what is it running on. if its designed for 220v (but that would normally be a EU700? or something like that?) and being run on 240v , it will be high....maybe has a 220v transformer fitted in a uk/240v case???

Re: Fuller FD42 Keyboard

that fuller with the extension, and, yes, rampack is mine 😉 if you'd like the dimensions of the extender board, give me a few days to dig it out (part of my 'round to it' pile) and measure things 😁
