Tubes!

Tube sockets mounted and tubes tested. 
The tubes I will be using are OD3 and OA3.  These are voltage regulation tubes.  One drops 75 volts and the other drops 105 volts.  In series they will drop 180 volts.  Therefore they will regulate the voltage to be exactly 180 volts for the nixie tubes.
