I dug out my TS-23B part chassis and pulled the VOT. I can't believe they riveted it to the chassis
The part# is really hard to make out. It looks like 25B792545.
I measure 11.5 / 650 ohms primary / secondary.
Your schematic calls for 9.8 / 770.
If you want it, it's yours. I'm still searching for knobs.
