Universal adaptors almost never supply enough current for machines like
the Poly 800.  Even if the voltage is right, when you apply a big fat
Poly 800 to the terminals you may as well be shorting it with a piece of
wire!  You need something that puts out 9V and at least 700mA.  More
current is good, less may make it unreliable.  Anywhere between 8V and
10V should be "close enough", but try and keep to 9V - and definitely
not above 12V!

I use a 9V 4A (yes, 4 amps) regulated power supply for running a bunch
of 9V-powered synths and effects.  It doesn't even get warm, unless I've
got everything on all the same time.
