Hello. - Apologies if this is a double post: I replied a few days ago, but my response has not appeared. Frankly, this new "Yahoo Groups" style is utter rubbish.

Thanks for your response.

I need to find the dimensions because I'd like to rig-up an adapter myself to use with a spare transformer I have already. - This is something I've done in the past successfully.

Perhaps I should contact Roland themselves: They ought to know!

Thanks for the thread you linked: I used it previously to discover the correct polarity of the plug since, oddly, Roland neglected to stamp it on the back of the drum-machine.

MDA.
