Spring Retainer for 6V6 / 5881 Short Bottle Tubes

A spring retainer for use in applications where tube is suspended upside down in the amp chassis. Keeps the tube firmly mounted and prevents tube rattles and related problems.  For use with mid-size octal power tubes such as 6V6, 5881, short bottle 6L6 / GZ34 tubes. 

Note: We recommend use of Silicon Ring SILRWELT41 in conjunction with this retainer to reduce rattles and microphonics.
