JJ ECC83MG Gold Pin with fully Balanced triodes. If you need pairs or multiples of this tube matched to each other use this option. These tubes have perfectly symmetrical performance between triodes and are ideal where total consistency and repeatability from tube to tube is desired. The Gold Pin tubes have a very open and lush character. When overdriven they have a very smooth and singing tone that's less gritty and less aggressive than the original ECC83MG. All Gold Pin tubes feature internal components that have been selected off the assembly line and treated differently during the final construction process. HIFI users can expect increased bandwidth and a smoother presentation with the Gold Pin tubes.
It has plenty of definition even when used in an amp with lots of gain and the microphonics are very low.
