ELECTRO-HARMONIX 12AX7-EH GOLD
Pay as per month with Paybright
This is the gold pin version of the popular Electro-Harmonix 12AX7-EH.
One other note about the construction of these tubes is they have filaments that are almost completely encased in the plate structure. They often don't "light up" when working properly. This is not aproblem, it's normal for the gold pin 12AX7-EH.
