How much hv should be present at the anode without crt and yoke in circuit.

No telling what the answer is without the yoke in circuit. It is a vital part of generating the high voltage.

Exactly!

It's all part of the tuned circuit mentioned before, a big feedback loop, I kinda think they made it that way to protect the CRT if something were to fail, if the horz sweep was not right, the HV would shut down and protect the face of the tube from burn.

Does set still have 2 hoz out tubes ?
It would be interesting to see if they are drawing the same cathode current.
OK on discs. Almost all I changed were burning or cracking open or dead
shorted. BUT ?? If you try them I would nip one end then hang in.
Maybe someone still sells an assortment, I would go with 1KV ones.
BTW its getting long so what is the voltage on the G-1's of the
hoz outs ?
