Yikes - sounds like tube problems to me too. The wires running from the tube pins to the numbers is usually coated with something to prevent them from glowing. The tubes could just be bad. However, if the tubes are run at higher voltage or current, the wires at the base of the tube can glow. The wire glowing can become permanent over time.
If you do a search on cathode poisoning, you'll see how people run tubes at higher current to burn deposits off the digits, but it can cause problems like you're seeing. You could try lowering the high voltage power supply voltage to see if the wires stop glowing, but you want the numbers to light fully to avoid problems over time. Sounds like your kit is fine. :) On Thursday, November 24, 2016 at 12:34:34 AM UTC-6, BooBooBeGone wrote: > > Hello all, > > I bought a PV electronics Spectrum kit with Z566m tubes. > I have "bombarded" Pete with stupid questons through this build, so I > guess he is geting fed up of me,(I would be anyway) so I'll ask some > questions here > Did the first tube test, and in 3 tubes some of the lead in wires glow. > > Tube 1 all wires glows > Tube 2 wire 1,2,3,4,5 and 9 glows > Tube 3 wire 9 glow. > > It does not matter if i put these tubes in another socket, the wires still > glows. > > voltage is 170 volt > > Is this normal? > Is it possible to do anything about this? > Will this have any influence on tube life length? > > -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
