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.
