Hello, Dan!
Over the last few years, there have been a lot of complaints from PS-2 owners about hum on various internet forums. All of these problems concern units with 230V power supply.
For example, here is exactly the same problem. It is described in great detail:
Why hasn’t Fryette solved this problem yet?
I created a separate thread on this forum and asked if there are any owners of 230V units without hum problems. Not a single person responded.
I would really like to buy a PS-2a on Thomann, but I don’t want to face the same problem.
Please help all PS-2a owners who live outside the US.
Thank you so much!
