Hi, in this page **broken link removed** the PL504 headphone amplifier is presented that uses a pl504 and no output transformer.
Can I somehow parallel more than one PL504 to reduce the output impedance so as to be closer to 8 ohms? For example if I parallel two tubes will it be 300R?
How shall I parallel the tube, does each tube need to have it's own resistors or just parallel them pin by pin?
Is the output power doubled by paralleling tubes?
