somewhere out there in 2nd hand synth land, there's a rogue I modified
for the mid 90s indie band tiger, who played their bass parts on the
thing. one of the oscillators was lowered an octave, & the power
supply was replaced with an internal toroidal transformer & an IEC
socket on the back panel. a few months after I did these mods, I took
my own rogue to a gig in holland & forgot the power supply- thought
I'd modified mine aswell, y'see.... :-)
anyway, it's worth considering this rather than carrying on with the
wall-wart.
duncan.
