Paralleling output tubes lowers the reflected impedance seen by the load, it does not alter the voltage, much, as global feedback adjust for "missing" output voltage.The word "match" implies equal values, and as power amps being voltage sources, they ignore this, (in theory) so rather than "matching" impedance I would just call it "suitable" impedance.Drive an 8 ohm load with a 2 milli Ohm source, no problem. No matching needed
