korg b1 help

Some unknown brand can bring noise and don't want charge preamplifier psu CRC filter capacitors.
Done verified good model's are a guarantee to avoid this issue.
Check the one like a Triad brand from Diyaudio store,
Another solution can be try 24 V smps from your local shop (no shipping cost)
and if is noisy then you can get eventualy money back.
My Diy Korg B1 work great with Philips laptop computer smps brick and is nice quiet 🙂 Good luck
 
Where I live (USA) and when I lived in Japan there are "thrift" stores or "recycle" shops. Basically junk stores where people donate items and the store resells them. A popular one in the states is "Goodwill".

These shops often have hundreds of DC wall wart power supplies. And 24V is a pretty popular voltage. Usually they can be had for $1 or so. So you can afford to buy a couple and try them out. I've tried 2 different ones...both did not make any bad noises.

Might be an option if these stores are open where you live.
