10) Added transformer wires and performed lots of measurements

The measurements can be seen in this spreadsheet (screenshots added to this post for convenience): https://docs.google.com/spreadsheets/d/1481s1TLiWwiSgU1UrxgSDXqTYwXUrslObALEj7EQkOw/edit?usp=sharing

Most of these measurements were performed on yesterday's live stream on YouTube: https://www.youtube.com/live/wQLbCVtNCCQ

I measured both transformers at all thee windings with all the other windings open and shorted. I also measured the two "tube" windings in series as separate entries.

Any interesting patterns? Tell me if you find any!

So far I've seen that the one tube doesn't "see" whether the other tube is shorted or not, *except* when the wire joining the tubes is shorted. Others in this thread has argued that the coupling between the two tubes are so low that the halves of each transformer could be seen as its own transformer, only connected in series by the wire winding.
