Danny if you can visit the NW, a couple are yours for a nominal palm-crossing (no blood required but I did have to pay for them).

Oh many thanks! Ill see what i can sort! Ill be close by before the meet! I often sit here and say i cant take no more in but an offer of this extent i cannot refuse!

lovely tubes very good that you found these. i think i have a 18w the same colour and a 36w both gb ge

You've hit the jackpot! 8' 85W/840 has been on my 'wanted list' for ages. I wouldn't mind purchasing 2 or 3 of these from you if possible?

Sure thing Andy. June's the month.

what colour are these then in old money, as i only know the old colours of the 80's and before. are these like 3 times the brightness then of an old tube even if its new old stock?

Thanks Nick!

these are 4000k cool white

why do so many collectors sing the praises of the later colours? i can see the benifit of being brighter in a shop etc, but in your house, old tubes are bright enough. Got a couple of 8 foot warm whites burning in my kitchen atlantic twin, with clipluve, and thats too bright for me really

840 is cool white phil probably not a colour you would be in to!

not really , ok for a garage or supermarket

they maybe newer but they are still rare nowadays..

Yeh these are really rare I could of had loads of these but stupidly didn't bother I was only just qualified and working up high by myself in a busy shop on AA3s that were hammered!

i'd use em if i had a job for them, but wouldend hoard them personally

Few years time phil this will be extinct in fact they are pretty much already they are over 10 years old

did they make a polylux warm white?

Yes they did they are colour 830

These are a good 10 year tube!

took a 35 sox out the other day, 13 years old ! what hours you burning your 8 foot 85 watt at 10 years life then?

lampy your kitchen must be big to accommodate an 8' twin. I bet it looks amazing with the Clipluves. Last time I saw those was in my school art room on single 5-footers in 1976-1977. (PS I bet you'd be sold if you saw the effect of 840s, especially with how triphosphors bring reds screaming to attention in comparison to non-deluxe halophosphates.)
