Where did you get that many GSA10Gs ? I'd been collecting dekatrons since 2003, and I don't have a one of the GSA10 or GCA10. Last haul of odd dekatrons, I got, was a half dozen GC10/2Ps. That one was lucky on two points. The more important point is that the supplier turned out to be a real snake (understatement). On another audio tube forum, an eBay buyer describes how this same guy swindled him on a $10,000 deal ! I've looked at the Ericsson datasheet on the GCA10 & GSA10. I can tell you right now, that you can drop that voltage an additional 30V. Instead of 475V+/-25V, you can use 445+/-20V. Ericsson "Digitrons" have 200V strike voltages instead of the 170V, of a more common nixie. Plus they don't show the interstage circuitry. That interstage circuitry can be powered by 250V or less. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
