I would advise against using any power supply that has removable tips enabling reversal of the polarity. This is a disaster waiting to happen. 1 split second of absent mindedness will fry components inside your Poly. You might decide to test something else and swap polarity and then forget to change it back again.
Just search on ebay for Roland TR-606 power supply and see what you can find. Something with a permanently set polarity is safer. Stick a label with Poly-800 only
written on it to the power supply if you must.
These power supplies are usually all switched mode ones of at least 500ma.
Remember CENTRE/CENTER NEGATIVE.

I’ve been using 300ma for years. No
problem. The only thing that is really critical is that it has to have the
center pin NEGATIVE. This is backwards from most AC adapters, but fairly normal
for a lot of Korg and Roland products. The size is hard to measure but I
believe it is a standard 5.5mm outside, 2.5mm inside diameter.

So 300ma is good? I saw 800 there as well. Also the
adapters at radio shack have adjustable tips. Which on do I need? I'd prefer
not to schlep the Korg there. Thanks again. This is a helpful group!
