At Murri's Electronics, the man says, "I put my tube tester in storage. Only needed to use it a couple of times a year. You should try A-Gem." A-Gem Supply is the place with the bad tube tester.
On reading Old Coot88's comments about very low voltage at pin 8--well, it does consistently read either 8 mV or -8 mV.
Questions:
From the data--voltages, resistance--is there any indication that either the tube or the coil is bad?
Please identify for me high impedance/low impedance windings and which is primary/secondary.
Fortunately I followed Phil's advice to not solder the coil connections until the thing actually works. In fact, I've gone one step beyond:
I'm inclined to buy another tube and coil, revert to Phil's original design, and rewire it as if starting from scratch. That will wait until I open the Atwater Kent 37 and find out what I need for it.
Until next time, thanks much, and as my old professor said, "When you hear hoofbeats, don't look for zebras."
