I would have updated the high voltage power supply to

PS. Where do you find a 300 V transformer ... I may build one
some day.
If you don't want to scrounge surplus stores, or wind your own, Hammond
currently makes a couple that would work. They are the 269BX and
369BX, depending on whether you want "universal" primaries or not.
Their high voltage secondaries are 300VCT, and they also have the 6.3V
windings. They're a bit larger than necessary, being rated for 2-3
times the power called for in that design.
