PCBs and general enquiries

Hello everyone! I'm building the SLO 100 for a friend, and I am really struggling with finding appropriate transformers. What are you guys using?

I'm in the US. I found an EU seller, but he doesn't ship to the states.

I could purchase the Onetics set from C3, but they're over FIVE HUNDRED DOLLARS. That's (respectfully) insane.

I've emailed Hammond to find an appropriate set, but they don't have anything that matches the specs for the Power Transformer. Any help is greatly appreciated. I'm willing to step this build down to 50 watts or literally anything that makes this cost effective but still fully functional.
