Re: [TCML] GU5B VTTC
Hi list
I added a staccato controler to my VTTC and 2 more MOTs on my source (that's 6 little MOTs in serie-parallel).
The second light was very satisfying:

Re-tuning for streamer loading gave much better sparks, up to 80 cm:

The power cord is hot after short runs even at such low pulse rate, but I think that this tube would give much better sparks powered by an appropriate plate transformer (too pity that I have none, even more MOTs). I enjoyed to work on this project.
Best regards
