Hi all, I am trying to discern what distance is really necessary for a B27A & B26A sockets when they should be made with Nixie-pins on a PCB, the B27A pin socket is used for GSA10G and the B26A is used for Burroughs BX-1000 series of tubes.
The original PCB mounting socket that I've seen have at least 5 millimeter between the pins as they are bent outwards and longer than the standard straight Nixie sockets used for PCB mounting. getting the same spacing with Nixie pins would require that I bend the Nixie-pins and that would complicate things like mounting. The original B26A socket has some 3.17 millimeter between the outer pins (17 pins (actually 18 but one unfilled position) with an 18.2 millimeter diameter) and 3.87 millimeter between the inner pins (9 pins with an 11.1 millimeter diameter). The B27A socket has an extra pin in the center which is the anode with some 500V on it and that sits approximately 5mm from the inner ring with pins. Now I I haven't taken into account the solder pad size for these figures so the distance between solder pads makes the actual distance shorter, for the Anode on the B27A socket I can solder a wire so i wouldn't have to route it between the other pins, but for the B26A socket I would like to route the wires between the pins making the distance even shorter between solder pads and wires. The Burroughs tubes has a maximum of 300V between the pins and the GSA10G has some 240V between main Anode and a Cathode and some 225V on the Auxilliary Anode when running. Any help is highly appreciated! /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
