Ok , whatever you say , although a 2A3-40 is a 300B with folded filament and the driver tubes you suggest do not make sense for use with this tube . It will work but I suspect significant HF loss and major issues when driving the 2A3-40 grid close to 0V . A 12AX7 (and I'm sure this applies to 7B4) is not really a good driver unless it is driving a pentode . In fact it has higher Rp and is much less linear than 6SL7
I think you're barking up the wrong tree regarding this mu of 100 thing and also your idea about 6AV6 . If you tie the diode plates to the triode plate , the cathode will start pulling quite a substantial current . The triode section in terms of signal will be 'shorted out' .
Usually redundant diode sections are tied to the cathode .
