So operating the filament of a new one for 48-hrs does nothing to getter the tube? R L MEASURES, A

Jim -- A 1000A rating is barely enough for a tank Q of 15 and a tube such as the 8973. (18v, 650A filament) > cheers > R L MEASURES, AG6K. 805-386-3734 r@...

My discharge stick is made from varnished bamboo, a 1000-ohm, 100w resistor tap

Guillermo, Yes, I remember. I wanted to tell you that the resistors off the base to ground are correct, and most likely are 10 ohm carbon comp type. However, I've never seen one base of one transistor

bloody capacitors are common in larger commercial amplifiers. ### Jenning's only list's one water cooled cap...1000A ! ### Jenning's makes one air cooled cap... abt 17" long...8" diam. 400A.... [no

Don't know if you were referring to me or not. 73 - Doug N9XTF internet?,

Well, do you remember my last post about that VHF solid state amp?. I emailed Henry radio asking for data about the transistors and if possible a circuit schematic. I think it was 5' later I received

Hey all, I would like to build a water cooled GS-35B for 2 meters. Although not set in stone, the current design uses a 3" dia, 1/2wl plate line. Am I dreaming of routing the water lines out the HV

zirconium coated anodes... and gettering is done when tubes show colour... aprx 800 deg C. I'm inclined to agree. only? ###### It can't !! 3-500'z don't have any internal filament heat activated

Current flowing has nothing to do with the rate at which electrons are being boiled off of the tungsten dicarbide (W^2C) layer on the filament.

What kind of flowers do you want, Tony?

To me that is hard to believe. I never recognized any emission current higher then a few microamps without voltages on other electrodes of a tube. Without anode voltage there will be only a cloud of

So how can a 3-500 be gettered by running the filament only?

Amen, Jim, and when thoriated-tungsten
