JJ ECC803S Gold Pin with fully Balanced triodes. We recommend these for long tail phase inverter stages which are common in most push pull circuits (most all guitar amps), or anywhere that symmetrical sections are desired. 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 ECC803S. HIFI users can expect more bandwidth and a smoother presentation with the Gold Pin tubes. All Gold Pin tubes feature internal components that have been selected off the assembly line and treated differently during the final construction process.
We recommend these for long tail phase inverter stages or anywhere that symmetrical performance between triodes is sought. It also gives you the plate current and transconductance spec for each triode which is nice if you're trying to keep records or maintain exact consistency from tube to tube. If you need multiple matched tubes please see our "Balanced and Matched" option.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.
