Dave Smith Instruments SYNTHESIZERS

My mono desktop is acting kooky - sometimes when I plug in the power
cable, it just sits there, dead. Other times I'll be playing along and
suddenly it will reset or randomly switch to another patch and start
the sequencer, or other haphazard behavior. I bought it second-hand
and have had no other problems other than that the original owner
crimped up the power cord in some sort of little box next to the plug
(strain relief or something?).

Anyone has weird power issues? I snapped apart the actual plug and put
it back together just in case it was something with that...
