? Many models of Henry amplifiers do not use a peak discharge-current
limiting glitch resistor is series with the hv positive lead. Most of
the hv transformer failures I have heard of in Henry amplifiers were
associated with a noisy arc in the RF output compartment. .

? The SB-220's hv transformer is potted. Few reportedly fail. Henry
uses unpotted transformers and unpotted chokes. IMO, an unpotted
(resonant) choke filter is nuts.
