Beginning of a GU81M vttc

Finally got around to working on the gu81m vttc, got some resources, wound and coated a new secondary with a resonant frequency of about 650khz, and FINALLY managed to power the tube filament from a transformer rather than a bench supply but using another toroidal core as a choke to drop some voltage to make the backup UPS transformer output about 12V

Nice toaster. Great that you are building a vttc because I going to build one with the gu81m too soon.

A worked on VTTC next to some breadboard project next to a HFVTTC lol

I hope that UPS transfomer isnt the type that is wired as a autotransformer, veriry that there is no conductive path between the windings.
Otherwise this looks very good, please dont subject the tube to a lot of rough Handling.

~~Sorry to disappoint~~
also dont worry the tube is okay :P the mic is just very sensitive.. kinda just set it randomly and cant be bothered to edit the audio
