Thanks, pressing display on the DSP's only get the FW version (5.21) on the 18bit centre it cycles through a bunch of pages as you say.

I'll have a play with the MConfig and see what I can find

Thanks again

BTW - any idea how much a G61R PSU is (non Linear one that is) or their availability (I've seen elsewhere you are one of the guru's on this forum smile ), I know mine has been replaced once - but I think that was still best part of 10 years ago and don't fancy blowing it up just yet if there is something sensible I can do to prevent it!
