Without Hg vapour, there are lots of damper diodes like 6AX4 that will tolerate PIV quite well enough. 6W4, 6AU4 too and all are octal of the same pin-out, though with nearly 2:1 difference in heater current. See TDSL for data.

Damper diodes? They have a 900V limit between cathode and heater, so one can still ground the heater, while the cathode is at 900V!
