I was under the assumption that tubes only worked when they are orientated in the correct direction
some remarks i read on the JoeNet suggest this could a gorgeous hoax.
One guy ordered hi purchasing agant to buy and he promised to report, should the purchasing agent have success with it.
Me has no idea about how to generate the high supply voltage on the motherboard in a sane way but i must admit i would loathe having a multiplierchanin usng diodes and capacitors for that and i also would loathe to have a DC/DC converter for that. Best thing would be to have a an insulation trannie and use 110 or 220V from the wall outlet. But what willl the UL guy say to that?
The more i muse about it, the more it seems to be a hoax.
yes, there are tubes running at those voltages but the pixes clearly show a 6922 which is a special version of ECC88 or 6DJ8. Which needs about 80 to 100V at the plate. And then, unless you have a CCS as plate load, you need another 50 to 100 V across the plate load.JohnR said:You don't necessarily need huge voltages to run a tube, 35-40V will do it.
