Hello. Gary please excuse me for beeing absent this time. I was off grid. Please tell me how do you want to do to send me the supply. What I must pay? No offense! You can explain the functionament of the schematic, please. Also tell me the place where did you buy the transformer.
At farnell.com, tme.eu, I don't find any transformer like yours.

You Can't Buy this Transformer anywhere. I Designed it, than I Machined this Bobbin out of Glass filled Delrin Rod on my Metal Laithe.
I was Sure I could do this, But Unfortunately I am not prepared to sell it. I am using this one for a personal project of mine and it takes considerable time to make this type of bobbin and also wind it.
Sorry but I didn't think it would be so much work.

I understand about the transformer, but tell me the inductance of primary and secondary, the winding number of each and please post the schematics. Thank you!

Also please consider if you want one of these at exchange. I plan to give you one the photomultipliers or the X-ray tube . Tell me if the power supply is regulated?

Until now my working circuit is: I use the red HV resistor 82Mohm 5% and the long blue 100Kohm pot for the voltage divider. 555 as an oscillator with 1K,10K,1nF. LM358 that compares the feedback with the voltage provided by the LM385-2.5 voltage reference and multiturn pot(big blue one), and 1K resistor from the LM358 out pin goes to the 4N25(6 pins case in the middle) that grounds pin 5 of the 555. The mosfet is IRFP460. The transformer is E30 www.tme.eu/en/details/e30_15_7-3f3/ferrite-cores/ferroxcube/I use 400 turns secondary and 9 in primary.

I Don't have any use for those Tubes,
No my Circuit is Not Regulated. It is Not needed for my application.
