Nice! Those 304TL's do run red! I almost picked up one at the last local hamfest, then I saw how much people were asking for them (new): ~$100. WHAT?! They are neat looking, though.

While watching the video, I couldn't help but wonder a few times whether you knew you had the camera turned on wink wink

Cheers,

I knew my cam was on all the time :P

I bought this tube on ebay, i think i payed between 60-100 bucks for it.

Nice coil.. but really, couldn't you just set the camera still somewhere? And what are all the scary sounds in first video suprised

'have any info on the circuit? I didn't notice a feedback coil on it. Capacitive feedback from that copper ring around the base?
