Indeed George. Noise is a bit more around 15m but signals also. SNR seems to be the same.
I am very happy with the Wellgood. It's a very good replacement for the broken Wellbrook preamp.

Yeah I think it's a self resonant point. When I get some time, I'll stick the layout in Ansys HFSS and see what causes it. Needs a layout tweak, I suspect.
The SNR still seems to be better in that region, despite the raised noise floor, so it hasn't been a priority for me.

I wonder if George has seen this discussion? I would be very interested in his thoughts on the topic. @m1geo.com

That large amount of noise around 21 MHz. The same here at the Wellgood amp.
