Enticed by another VTTC this time based around the popular Russian ГУ-81М (GU81M). This seems to be a massively over engineered tube and able to take the hammering Tesla Coils can often give their primary circuits. I am being kind to this one. Although modular in construction, with a Steam-Punk look, I have as usual, crammed all the components in for a small footprint. This limits future modifications to some extent. Check out ‘Tested to Destructions’ video to see what these tubes can be pushed to.
