If push came to shove and you needed a substitute of a pair of type 50s you could use a pair of 6L6 tubes connected as a triode, with an adapter, using a resistor to drop the filament voltage to 6.3 volts from 7 volts, but a pair of China 50s would be better as you wouldn't have to change the bias voltage.
