Muti-Color Vacuum Tube Shield Aluminum Alloy 9G-55 Shield Caps for 9 Pin 12AX7 12AU7 12AT7 Tubes Pack of 5

Great for those amps you buy that some stupid stripped out the originals. Lol.

Fit better than my original. However, not aluminum. They may be aluminum coated, but stick quite strongly to my magnetic flashlight. 2 Stars off for inaccurate description. I would suggest changing the black and silver for other colors as I was trying to enliven my dull amp.

the right stuff
