The tube 6P15P can be used as a replacement for the EL84, 6BQ5 (6P14P). Only the grid voltage needs to be adjusted.
For class AB push-pull:
Less negative for fixed bias or the cathode resistance (common for both tubes) should be approx. 100 Ohm for automatic bias.
The plate current should be  30 - 35 mA.
Good solution is connect parallel resistor 330 Ohms to the cathode resistor 130 Ohms via switch, then both types of tubes can be used.
Pin 6 (G3) need to be connected with pin3 (cathode), pin1 must be not connected.
If you need so I can let you know more details.
