A new leaded glass compound is utilized to maintain vacuum integrity, balanced performance and ensure long life.
6CG7EH The 6CG7EH is a low noise, full voltage replica of the original 9-pin RCA that is exact in every detail. The silky sound of the original is maintained inside of an ultra rugged design that guarantees long life. Linear response and a low noise floor are maintained within this wonderful sounding tube.
