    There is no service manual for this model, only schematic.
    See in your PM box.

    Is there any reason why you can't post it here? I've been looking for the schematic too for quite some time.

    Usually because of non-disclosure agreements. This means if you publish them on the web you lose all your privileges with that manufacturer.

    Hello,

    Any chance of getting the schematic too? I'm very interested what it looks like.

    That was good, but after all that work he was about to change over from rheostat type and take the bias off the pot wiper. No, no, no!
    Good thing the guy from talkbass came along and showed how to do it and keep the much safer rheostat version.

    You also gotta love that he put that electrolytic cap directly on top of the 5W resistor.

    Mr. Theory needs to be introduced to Mr. Practice.
    I'll bet he has some letters after his name.

    edit: nevermind, the cap over resistor was done by the talkbass guy, even though he had the better circuit.

    Hi,

    I'm looking for the Ampeg PF50T service manual, a schematic would also be good.

    Thank you very much!
