Tektronix 453 High Voltage Transformer

[Douglasfir]

Hey guys, I'm in need of of a guide, or some assistance on rewinding a Tektronix 453 oscilloscopes high voltage transformer.  Upon placing an ammeter across F937, and brining up the line voltage slowly, the current climbs fairly quickly to about 800mA where I shut the power off.  I am told a properly operating circuit will draw somewhere around 2-300mA. 

A little background, Q937 was missing, (HV oscillator, equivalent to a 2n3055).  F937 was open,  When powering up slowly q937 gets far hotter than it should.  Checked 500pf doorknob capacitor on the anode and it is not shorted.  Power supply voltages (+12, +75, are within spec.)  I have scoped the base of Q937, and the waveform is there, but it is heavily damped. This is at 20us, and running reduced line voltage (about 40VAC).

I guess what i'm looking for here is someone that has a transformer they'd sell, or some guidance on rewinding mine.  I have never rewound a coil of this size and it seems like a daunting task.  Can anyone please help?  Thanks so much!

Please don't double post, it annoys people who have already helped you... and the Mods. https://www.eevblog.com/forum/testgear/tektronix-453-high-voltage-transformer/

I am not double posting, I am looking for assistance in rewinding the transformer.

It relates to the same topic and the same transformer. Post the additional stuff that you listed above as a reply to the existing thread.
