    Preventing Avalanche Issues with the SBT-10 Geiger Muller Tube
    A radmon.org user was having avalanche issues with their SBT-10 Geiger Muller tube. Doing a little research I found a little information stating that each anode on the GM tube (there is ten in total) should have it's own quenching resistor. I have mine set with a 10Mohm on each anode (see pic below) and appears to work OK, although I haven't had it running for long and just some simple tests. When I got it I scoured the web looking for info but it seems there is very little. One recurring theme was that the voltage and resistor(s) did play a very big part on getting correct counts from the
