It's not just the filaments but how to mount , and you'll need dissipating caps . You need to build a test rig before even starting a breadboard , a lot of VT127 have problems such as lost vacuum or severe gas . I ran mine in zero bias at 575V / 70mA with 5k OPTX , at this op point the valves hardly cherried up . I suppose A2 at much lower volts and lower load and higher is also a possibility . It would be a bitch to drive like this though
