Default Komuro DC 300B crct w/ 50dht?

Hi guys,

Is there a way to implement Komuro's DC 300B circuit for a 50dht while keeping the triode strapped pentode's choke-loaded anode output Z well below the 10kOhm max limit (for the 50 triode)? Or is the only option LC coupling (grid or also plate chokes), besides IT coupling of course?

I may try it using a 76 as input (unbypassed cathodes). Could this circuit's driver stage be a good candidate for "series bootstrap biasing"? Thanks.
