    How big of a problem is it that a transformer may be making slight contact with the speaker magnet?


    Thanks!

    Hard to say, I've had them within 1/4" of the output tranny without problems. I've mad these little plates to tilt the tranny away from the speaker before to avoid drilling a hole in a vintage chassis:

    That is a really good idea.

    Just another day in the life of a Rivera Hundred Duo.

    No issues, no rattles. The speaker baffle is quite thick and solidly mounted so there is zero movement at the basket & magnet.

    You really do not want them touching. Even a bit of an air gap does a lot. the magnetic flux of the speaker can go through the transformer and it may saturate early. If the transformer is touching the metal part (assuming a ceramic here) it is not as much an issue. If it is an alnico don't worry about it. If it is a speaker with a cap over the magnet structure, why are you bothering us? ;)

    it’s a 10 inch greenback, so a ceramic magnet. In order to make it fit, the plastic cover has to be removed.

    Can you fit a few sheets of paper or a business card between them? Or maybe something a little more substantial than paper. I am guessing there will be a little vibration involved. A couple sheets of a pop can.

    I could put some electrical tape between the transformer and the speaker. But, not sure if that’s a good idea.

    I've seen an amp chassis with the transformer pivoted away slightly from an overly large speaker magnet. Three new holes drilled in the chassis made the tranny stable

    Beer would be best.
