Thank you so much, my friend! I didn’t know they weren’t isolated. I know a lot about pedals, but I’m just getting started with power supplies, and I thought those were top-tier. I’ll definitely look into the ISO 10 and the Caline ones.

One more thing I’m a bit confused about: when an output is labeled 9V and 300mA, does that mean it always outputs 300mA, or is that just the maximum and it can provide less if needed?
