Description

Surely this famous JG 12AY7 GENERAL ELECTRIC double triode original made in USA of Military grade is a certified tube for its superior quality with special Audio performance. Probably one of the best 12AY7s, produced at the end of the 1960s, it has a very sturdy structure with a dark gray box plate and a square getter placed at approximately 45 °. This valve, due to the special use and positioning to which it was addressed, was extremely selected at the origins and cryogenically treated; also for this reason, today, its performances in Audio set but in particular with microphones are amazing!
