Was that the burgundy one-side adhesive stuff? I found it useless for CDs but great as a damping layer between cartridge and headshell.

I have an old Sargent Rayment tube amp I scored at a garage sale and I get the drift that the copper is used as a conductor plane since grounds of caps and power cords and other stuff is connected to the chassis. It has a 2-pronged power cord.

No, nothing self-adhesive, just kept in place by laws of gravity....

I totally agree. Heat can be a problem , tho...

pretty alternative? I know a guy who owns "art speak" a modding company, he puts cork mats in amps(pieces of cork floor tiles) against the metal plating.
Ofcourse a guy who puts tarmac in his breakfast cereal is more alternative but that's not the point here... To apply to the subject: if those amps were built from wood in the first place they would never need cork dampening (and lack the closed-up sound that no addition can cure once metal is envelloping signal circuitry).

imo that's the main backdraw... Chamfering around the tube holes + mounting iron above the chassis should solve the worst of problems, I can imagine chassis heat dissipation can be more of an issue with certain high power tubes.
