    It means it has a built in Pre Amp.
    When turned on it increases the gain of the signal when receiving, or another way to say it is, it boost`s the signal coming into your radio when you are listening.
    As for what class of Amp it is, that depends.....there are so many copy cat amps that have a Palomar name stuck on them the build vary `s from unit to unit.
    If it is an old TX100, they were built for low drive, about 3-4 watts or less, and my guess is a couple of MRF 454`s in it.

    A bi-linear amplifies TX and RX, but neither are linear.

    The term push-pull has a whole different meaning when talking amplifiers than that. I suppose in the CB world a push-pull amp is an amp with a preamp for the receiver but in reality a push-pull amp is an amp with a pair of tubes/transistors with each of them conducting on half the RF cycle and combined at the output usually through a transformer type winding instead of simply being in parallel.


    Me too.

    Now you know Pat. ;)
