I believe the oscillator operated at >100Khz in burst mode.
The huge HMV model 1820 TV set employed a separate EHT power supply to provide 12KV for the 21" round faceplate metal cone CRT.
The Emiscope tube soon became obsolete and the service replacement was the Mullard MW53-20.
I'll find the EHT generator circuit and post it up later today.
