I purchased my modwave from the UK via preorder back in june. Its here and sounds really great - but - im using my wavestate ac adapter, because, the plug it shipped with was for the UK. It has that converter so I can switch it out with one of those rotational pieces.

I reached out to korg support but don't expect to hear back just yet. My question is to do with two possibilities on after market products, seeing as I cannot find any ka390 power supplies available for separate purchase [that i could find].

1. Does the converter plug that fits over the power supply have its own power 'handling' properties [i.e. lets say it fits the same way on the adapter, will it have problems with voltage, in other words, will its design differ in any electrical way if i get an after market one that ships with a different one, say this micro usb one [id only use the round usa converter/connecter]?

2. If I choose to go entirely with an aftermarket ac adapter with close-enough-ish characteristics, [and this is the closest i found so far], would it present with any operational issues for the synth going forward?

fyi, the properties of the ka390 power supply seem to be

input 100-240 v, 50-60 hz, 1.5 A
output 12 v, 2.5 A, 30 W

My Wavestate PSU clearly says it works with an input voltage of 100V to 240V on it. In short, it's one of those bog standard universal switching power supply units. All I needed to do was swap out the Plug Socket connectors it came with for the ones we use here in Ireland.

I'd bet the PSU for the Modwave is identical in every single way, so just have a read of it.

Thanks,

yeah i went ahead and bought that myvolts us plug for ka390 replacement adapter on amazon. Seems to meet the power requirements.

Its funny how you can't [or maybe I could have?] simply get the rotational converter piece for ones country-plug, just on its own.

Thats how this stuff goes sometimes.
