The 6CK4 is a triode and has similar mu, gm, and rp to the 12B4. I can't use it with my current circuit because of the filament requirements.The choke from handmade certainly seems like it'd be a good choice for a plate choke considering the ratings. I'd be curious to know where the choke's resonance point is at.
My visit to the handmade site pointed something out to me: the hammond 125E is not airgapped while the 125ESE is air-gapped. This kinda makes me uneasy to recommend the 125ESE for this application because the air gap reduces primary inductance. I think I'll stick with the 125E for now.
