Personally, I trust a 20-year old transformer-based PSU much more than a new switching-mode PSU made in China...

I recently purchased a genuine Yamaha PA-130 PSU for my MU80 as I no longer trust the 20 year old PSU that came with it, but it's a bit of a struggle to find a decent replacement PSU for a SC-55. Looks like Roland has not released a newer version of ACB-240 and I don't really trust all these third party compatible PSUs available on ebay.
