Power cord upgrade for Rowland 8T

i'd love to plug my jrdg 8ti directly into the wall but find it works only when i plug it into an ac oulet. ;~) actually, yes, i do not use a "conditioner/power plant" or such; i do, however have dedicated 20 amp lines with hospital-grade outlets. as for cord lenghth: there have been numerous posts on the subject. as near as i can fathom: you shouldn't have any problems if you stick to the "standard lengths" offered by your chosen manufacturer.
