SUBSTI-TUBE 928 Description

A adapter which allows the use of the 9-pin EL-84 tube to be used in Class A amplifiers such as the GT Solo Single, THD Univalve, and other single ended Class A amplifers.

This is not for use to convert Class A/B amplifiers to Class A, and should not be used in Class A/B amplifiers such as most Fender or Marshall amplifiers.
