how to cover unused tube socket chassis openings?

[pula58]

I have some un-used openings in some a chassis. They would fit a 9-pin preamp tube (3/4" hole dimater). Does anyone know of something I can cover the unused holes with?

I picked up some chrome ones from Ace Hardware.

Do the metal ones rattle at all? Anybody know? I have a spare hole on a chassis that Id like to plug as well. Im just not sure if the plug will rattle or not when the amp is in action...

Weber also makes screw-on cover plates for socket holes...the CP8 (octal)_ and CP9 (noval).

I always do it from the inside of the chassis with the sheets of aluminum from Lowes or Homedepot. Just cut or trim in to shape, drill a few holes and use the standard 4 or 6 hardware to mount. You can even use the thin flashing aluminum and cut it with tin snips.

I've used the nylon Keystone ones from Mouser with good result:

I do the same. Just about any scrap metal will do the job, and flashing works great. I usually cut a square or rectangle to the appropriate size. No need to be more elaborate. If already drilled for tube sockets, the screw holes are already there. If you have concerns about rattle (never had that problem, a bit of silicone will create a nice cushion and you can trim off any unsightly excess very easily.
