  • converting old pa amp for harp amp

    can anyone tell me how a amp with 4 ,6AB4,s and 2, 12AX7,s will work for a guitar/harp amp this amp has 4 mic outputs or inputs what ever you call them

    The 6AB4 & the 12AX7 are both triodes.
    They are generally used as preamp tubes.
    Not that they cannot be setup as output tubes
    It won't be very loud, that's for sure.
