Don't be a dick. Its ridiculous because of the required space on my small chassis. I have many amps. None use a choke on the input. This is a small class A single ended tube amp.

Fair enough on space—small chassis are a pain. But input chokes aren't universal; plenty of boutique tube amps skip 'em and stay quiet with better grounding or ferrites. What's your hum source? Power supply ripple?
I already explained it. I think I may be finding your limitations in conversation.
