RE: Amplifier input stages and power supply boards

In theory, yes, but I've not driven more than a pair of output tubes with the input stage. You would be well-advised, in the case of 3 pair of output tubes, to use the interstage coupled input stage and connect the interstage transformer for step down, in order to drive the grid capacitance more effectively. I would still use the LL1692A, but connect it 1.75+1.75:1+1. In this case, it's much like driving one pair with 1.75+1.75:2+2.
