sansamp power supply question help!

[bbq dengue]

I've got a tech21 & need to know if a replacement power supply will work...does it take a center positive or center negative power plug??? Help!

Any standard Boss-style 9V power supply will work. IIRC the standard boss ones are centre negative. I use a Visual Sound 1spot.

Thanx. Excellent. Negative centre does it. I don't have a Boss power supply but I've got an old DR drum machine which I used to cross check a center-neg 9V which worked all around. Thanks for the help, I'm back on the sansamp.
