If you refer to the RF choke (L11), yes, you are right, though I am not sure about the ringing. Ringing usually is suppressed by snubbers, but here we do not have very fast transitions, and if anything, inductance is not a very typical component to help with ringing.
L12, well, it is the filter, so, yes, quite replaceable by a resistor, considering the 1uF is already there, and in R73A the same cap is used with 20K instead of the choke. Then there is another 20K plate load.
I will try to find that choke, or at least calc the inductance, and see what can be done. Worst case, yes, a resistor will do.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
