12/24 volt tubes
are the low voltage tubes mainly good for unity gain or low gain in a preamp? i haven't found any amps using one in the output stage e.g. headphone amp.
a forum search says there's no substitute for high voltage. |

6GM8 and 6DJ8 are commonly used in low voltage tube amplifier circuits, although for a headphone amplifier 24V is probably below the lower limit even with these tubes.
And yes there is no substitute for higher voltages.
