it's a glv1,I don't have a multimeter,but today I'll see if I can find one in town
It's very possible it's pumping out more volts then I think,because there is a huge difference between it and my 4.8 box mod. I'm using regular 901 attys,but I have no idea what OMH they are,not that it helps,but it happens no matter which atty I try
