Before I build something similar from scratch, is there one of those sitting in someones shack they want to part with? Just a board would be fine. If not, I can put something together myself. Just wa

I think I have read about this in the past, but not sure. I was using the amp on 10m working some DX. Went to shut it off with the power switch, but the amp stayed powered up. I ended up unplugging i
