HV transformer replacement

[trans]

One of the HV DC supply transformers in my 1990s era Electrostatic Research speakers went out. The input is AC Mains, and one secondary connects across a leg of a 2200m 6kv cap to the diaphragm, the other one connects to a series of resistors and a rectifier to the audio signal transformer. The only marking on the transformer is TDS 9629B. How can I determine the DC voltage and find a replacement. I don’t have a HV probe to check the other transformer. Are there any other options?

Can you post a good quality photo or try to re-draw schamatic diagram of your EHT supply?

Lukas,

Thanks for replying. I solved the problem by running DC voltage from the secondaries to the primaries, in effect reversing the transformer to a stepdown. The ratio is the same either direction.
