Yes, I'm sure you're right on all those issues. I've used SMA connectors in the past at work, but these boards are the first ones that have made it in to my play room, so I'm on a little learning curve. I think I should get these amps safely boxed up asap before anything 'unplanned' happens to them.

Just one other comment I noted about them, the gain is very dependent of the DC voltage; shoots up between 7 and 8 volts and then flattens out somewhat.
