How to dampen a small transformer?

Small transformer is bolted to sheet metal bottom. What should I between the trannie and the sheet metal to dampen trannie vibrations?

I think something as simple as a felt (or wool) pad can be used to damp a transformer to good effect. Don’t “dampen” it, though. That would be very bad. :thumb:

I would use small rubber blocks or feet between the Trafo and the metal board, not hard rubber or too soft rubber like Sorbothane, but mid density rubber.

Other flavors:
Soft wood
10mm Felt

if the Trafo runs too Hot you cannot use felt or rubber because of the danger of heating.

I used rubber washers, after 1-1/2 years of use no issues.

Hey!

    When I replaced the transformer in my pre, I tried faucet rubber washers and 1/4" cork cut to fit from cork sheet. I listened to each one for a while and at the end I preferred the cork board. Not sure why but cork sounds better to me and seem quieter. Care must taken not to tighten the nuts and bolts too much though.
   
    By the way, I used to use 1/4" sheet on top of my old Rega Planar 2's glass platter instead of the supplied felt mat, liked the cork better.
