    Google point-to-point build, look at some images, and get back to us.

    This man speaks the truth. Listen to him and either have a professional rebuild this mess or throw it away.

    The amp has a ground. I already posted this once.
    Here it is again.

    This is a ground wire.
    It is green. It is grounded.

    Some are apparently seeing one for the first time here and it is triggering a stress response.

    Thanks for the thoughtful post.

    Just wanted to point out (again) that the amp has a fully grounded three prong cord.
    The entire problem was in the ungrounded outlet, and the floating ground issue you described.
    Naturally, I have no plans to use the same outlet again until it is grounded.

    I wish I could close this thread.
    Some of these guys are going to have a panic attack. :eek:

    Hold out for just one specific example of the many "dangerous spots" that have been spotted in what appears to me to be a completely normal and relatively clean looking amp from 70 years ago.

    I feel like for the aggravation we should at least get to learn something.

    Maybe I should just dip the whole thing in gorilla glue.

    Folks are just trying to help. I humbly suggest that you update the OP with the outcome of the thread if you want people to stop posting solutions.

    Thanks, yeah I tried that days ago.
    We aren't allowed to edit posts that are more than a few hours old.

    I'd suggest that people read through technical threads before they make irrelevant or inane comments, but people love a good pile on.

    Yeah the edit lockout sucks. Especially on build threads where you want to keep the most recent schematic/layout images on the top post.

    Good grief ..... your girlfriend is horny (buzz) ..... and you didn't notice?

    Forget the amp, you got some "buzzing" to reciprocate before she finds another amp to give her the "Buzz".

    Read somewhere that keyboard amps of that era seldom had great consideration given to grounding because:
    A) It added to the expense of production,
    and,
    B) Unlike guitarists, keyboard players don't touch exposed metal so the risk of shock is minimal.
    This oversight would likely be very probable in an (intentionally) low wattage/budget amp.
    Not having an earth ground in the garage ain't helping.
    I, personally, would try to follow the advice of an electrical engineer.
    Just saying....
