how did you manag to keep the tube from redining for such a long time? my tube glows red in about 5 seconds at 1800V AC. just check out my vttc and you can see what i got out of it.

@lbochtler Ah yea, i have seen your thread on 4hv (i am Arcstarter, btw). It all has to do with tuning. Once you've calculated your secondary's resonance, you need to calculate your tank circuit (primary and tank cap)'s resonance, and it needs to be the same as your secondary. Also, the wine bottle capacitor is probably pretty lossy, can you buy stuff from ebay from different countries (like US)?you can get some proper doorknob caps for cheap. If you need help finding the primary freq i can help

This is AMAZING performance for a single 811A tube, can you please upload schematics with component values (this is just an Armstrong Oscillator, right?). I'm going to go try a lower frequency secondary on my 811A right now...

Meh, it did not send the message. I will PM you :-D.

YOU ARE TOUCHING IT!!!!

when the tube is laying horizontal you have to have the pins a certain way other wise you ruin the tube, says so on the data sheet

@lbochtler i got it working, its in resonence now. it runs vary cool too. also im geting about 6" sparks to 7" sparks at 2KV anode voltage. the idea with the caps helped.

@triggerhappy77707 i know that my cap is lossy, but the new ones have been in the mail for 2 months now :(. and thanks for the offer of helping me, i would much aprishiat it.

very nice, congrats!

Nice vid ! Watch more Tesla tech in "Wonderful electic lighting" by HorizonDelta ;-)

[sprogdiklis]

can you sent me schematics and how much winds you used on resistor with inductor and what diameter wire
