Anyone have the latest and greatest on who does transformer rewinding these days, especially potted transformers?

Home of GORT. A buddy of mine named the 813 rig GORT.
His fear was when I turned it on for the first time life on earth would come to a stand still.

I know the guy that bought out Gary, WZ1M has not started production due to health issues according to his website. However he is on youtube giving out advice. I came across these links http://ludens.cl/Electron/Magnet.html  http://ludens.cl/Electron/trafos/trafos.html that prompted me to do my own rewinding. I don't know anything about potted transformers other than they can be a mess when overheated!

I believe they do custom rewinding also.

Resurecting this thread a bit, is there anyone that knows where I can find modulation transformer data? Not just primary/secondary impedances or DC resistances but wire and lamination data and other pertinent information. I'm going to order my winder this week. I want to start off with a small interstage transformer, a Globe King mod transformer, a 3.2KV CT transformer and hopefully I will have the confidence to do a full size modulation transformer.
