Thats way cheap..but then I noticed its a vdc...he requires 9vac 2amp,same as digitech mfxs,Korg multitrackers etc etc
My guess R400 upwards and electronic places dont sell 2amp ac units under R600+
I would probably look for an old line 6 mfx or some mfx unit that comes with a compatible power supply on gumtree for the same price
Old nintendo p/s are 9vac 1.5a,will still work fine,check polarity but ive used one on an Alesis SR 16 drum machine and a Digitech GNX4 without any probs of overheating etc etc
The actual amperage required is much lower than actual amperage recommended/on p/s unit
The main culprits of burnt out under current p/s are ambient temperatures and actual current used by unit for a lengthy period of time,
ie: smaller 1a p/s run hotter when overloaded too much in very hot climates...
So for average 2hr+ jams all cool on even the small amp units,but leaving it on for 8hrs+ and going out for dinner and leaving the thing on is a no no
