Now that's some motivation to get a good, macro capable digital and taking some pix.
Do you have any preference to having the pic taken with the cathodes hot or cold? This makes the big difference with thoriated tungsten DH valves of course...:) cheers, Douglas
Thanks much. Normal pictures with cold cathode would be more helpful for people to be able to id the plates, plate color (gray, shiny black v/s regular black etc).
