Up for sale here is this set of 2 used vintage metal J-slot tube shields.  These are not marked with a brand and look a bit more modern than the others that I have for sale, but they came to me in a lot of vintage tube shields so I am guessing they are still fairly old. These are for 9-pin tubes, and will fit a 12AU7 or similar tube. These are in great shape with light wear.  They measure about 2" tall and 1" in diameter.  Please see my pictures for details.

All my tube covers are listed; I don't have any available that are not listed.

US shipping and handling is $5, and international is $18, no matter what quantity you buy. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. If you have any questions, please ask.

I have more tube covers and other vintage electronics listed--feel free to take a look!
