JJ ECC803S Gold Pin with fully Balanced Triodes. If you need pairs or multiples of this tube matched to each other use this option. The Gold Pin tubes have a very open and lush tone. When overdriven they have a very smooth and singing character that's less gritty and less aggressive than the original ECC83S. 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.
The Balanced and Matched selection allows you to order multiple balanced tubes that also match each other. This is ideal where total symmetry and consistency is desired. This is most commonly requested for Audio applications where parallel signal paths exist (such as a stereo pre amp or drivers in a stereo power amp). .The Gold Pin JJ ECC803S is based on the same construction as the original JJ ECC803S. The internal components go through additional selection and processing during assembly. After working with these tubes for several years we can confirm they do test more consistently and sound noticeably different than the original JJ ECC803S.
