Description

The pair of vintage push and twist shield are the perfect addition to your miniature tubes and amps. Made in the United States, it is a high-quality accessory that ensures your tubes are protected from dust and Electromagnetic interference (EMI). They come with set springs inside them. We believe they are for 7-pin miniature tubes. We tried a 9-pin 12AU7 miniature tube on them, but it's very tight.
