Got a SBT-11 tube. I'm happy with these Neon-filled transparent mica window tubes of the Russian/Soviet variety, in addition to being cheaper and detecting alpha, they also put on a pretty light show in low light or darkness!
@@mandarin1257 actually with the GMC 320/+ you dont need an anode resistor as the board has a built in one and i works fine, and the voltage is in the right range for the SBT-11A tubes

Did you just remove the tube and connect the SBT-11A and it works?
You may need to adjust voltage and you certainly need to adjust conversion factor, but yeah.
You also need anode resistor on the tube.

Nice :-) did you make a holder?
Cool!
