I've just repaired someone's Rogers domestic stereo valve amp. He wants
something doing about the 12 'loose' phono (signal ) sockets on the rear.
These are plated brass of the same material as paxolin backed
tag board. Thin plated brass strip curved both ways ino a cylinder
with a gap so of course opens out over time and use.
They are easily accessible as a side panel is removable
but anything better than just squashing each one with pliers.
Rubber Hellerman sleeve slid over each with 3-jaw expander pliers
is all i can think of but will it work?

It might, but would require unsoldering each to install. Considering the
infrequency with which these are usually disconnected, I think I'd just
'squash' em and be done with it. A dose of Cramolin wouldn't be out of
order....

just thought of cutting small grommet to encircle each then tighten
a small cable tie round each to avoid desoldering everything

Cramolin ?

cramolin = contact cleaner

If these are the type I think you are describing, one needs only to
very slightly compress the metal on each since it the gap...perhaps a
1/4mm or so. Usually these get loose from over use or from using plugs
with great gobs of solder on them..either added to 'tighten the fit' or
just badly made in the first place. If you compress the clip very much
you can damage the cylindrical insulator in front while trying to
insert the plug for the first time.

Hellerman sleeves - principaly used in UK military / avionics multiway
trident
or similar connectors. Slid over where wire enters the pin and the pin to
reduce possibility of pin to pin or stray wire filaments cross- contacting
pins.
Rubber sleeves placed on 3 way prong expanders (cue smutty terms relating to
brides) to enable assembly.
