Steve asked:

"This is an honest question, not a carping comment. Is bypassing the cathode
to ground at -350V easier or less critical than bypassing the screen at
+350V?"

You were probably always causing problems for your teachers - asking
difficult questions just to see if you could stump them.

The 4CX250 has 4 cathode pins.  So, if you are cheap and do not want to buy
the proven, but expensive, socket with the built in screen bypassing, then
it should be easier to bypass the cathode - since you have 4 shots at it -
to get a low inductance bypass.
