We have laying around one of the Korg SP-300 (which were made in Italy - they weigh a ton!)
- Have misplaced the original power supply. That thing was a HUGE black cube, getting on for the size of a small toaster. (We did in fact purchase it in I think France if that matters, maybe they are bigger there!)
Notice it is marked "21" volts. (And a whole amp, too.) Can this really be correct? I may just be completely wrong but device inputs are usually some small amount of volts?
Checking sweetwater etc, you really can't buy the original any more it seems
You can easily google "replacement for SP-300 power supply". But ............
.... example, link they are all weenie little boxes like this -
I've found in the past if you buy a "weenie" replacement for any device (example, a cheap weenie replacement for a modern laptop that needs a lot of juice), they just hopelessly fail.
(Indeed notice as well for some reason the voltage is not even marked on those.)
My questions are two,
Does anyone know if it's a hard fact that it needs "21V" input; perhaps someone else has one and/or the original (perhaps European) power supply
Does anyone happen to have tried one of the "weenie" replacements, which are only like $20 - will it actually even work?
