I got my boards from OSH Park after about two weeks. The boards look very well made and I can’t see any manufacturing errors on them. I’m sorry about the bad lightning on this photo. It’s hard with such a reflective surface.
PCB for my amplifier made by OSH Park
To get more than one isolated output from my frequency standard I have decided to build this distribution amplifier. It uses one input amplifier and four output driver amplifiers connected to transformers to get ground isolated outputs.
I plan to design a board and then have it made by OSH Park.
