Wow thats shit lol
|
|

Wow, mine has been on for 40 nights too and most days and it looks new still ?????
|
|

Get jon to make you a new tube for it lol

Don't even think it'd be worth the effort this was only £6 delivered! Maybe this one hasn't been happy with our 250-253v we have here overnight

I cant imagine the high crescent factor of the capacitive dropper ballast is particularly kind to the cathodes! it would be interesting to salvage the tube from one, and figure out its optimal running current, then run it on magnetic gear with heated cathode starting, and seeing how long it lasts

Thing I find interesting about these is the tubes do look handmade to me, and I could make one. The let down with these though is they use torch bulb fillaments, single coil therefore wont last long

The Crest Factor of a capacitor connected across the power line (without tube) is sqrt(2), this is not bad. The CF gets higher as the off periods at zero crossing are longer - but with a tube that might be dropping some 20V maybe the off periods are not all that significant either..... (i dont know what the arc V of those is but i imagine 20V-ish). I wonder why they went for a hot cathode tube when they could probably do with a CCFL with low enough voltage to run on 230V and not care about the CF
