Input filter progress

I’ve gotten some progress made on the input filter for the amp project. I’ve got some problems with the neutralization causing some problems on 21 MHz but hopefully I can solve that. I am not 100% sure it will even be needing the neutralization, and without it I have no problems at all to get a proper input SWR on all bands. I’ve simulated the tube input capacitance with a couple of silver mica capacitors.
