Am I reading that right, <5.5MBq in each tube? I have a couple of old
spark gap tubes with Cs-137 in them used to calibrate isotope identifiers I
have but being WWII vintage, likely not a uniform amount in each tube was
used. A pint spot on inside of the glass, but gas is likely easier to fill
Ooh, barely $108 each!

Hello everyone,
In my obsession with Nixie calculators, I recently acquired a Dietzgen
ESR-1 which is a rebranded Casio FX-1.
It required the usual replacement of the power supply HV caps and a pass
transistor and cap in another regulator circuit.
After all that, it is still 95% DOA.
Just tie the anodes together

I made some new tests. I mounted 6 IN-12 tubes on the clock board. I
noticed that there were 3K resistors on board. So I plugged my tubes
directly into the board without adding any resistance. It worked directly
at 170V.
