You will be fine with the ECC83 tubes, especially since that is what Doc has on the Z tube info on the website. Doc tries the best he can to use current tubes that are readily available. It is possible the website you were viewing with the "s" at the end just meant plural - more than one EC883 (s). Last Edit: May 3, 2021 at 8:04am by "Z" Steve. A review of the JJ ECC83S vacuum tube. The JJ ECC83 S is substantially different in construction from the other 12AX7 types considered here. The JJ tube is made with an advanced technique known as "frame-grid construction" first pioneered by Telefunken. Frame grid construction is most commonly associated with tubes such as the 6922 and 6DJ8 Development of ECC83 in Europe. The ECC83S is a European designation for a popular dual triode vacuum tube. Primarily known for its high voltage gain and versatile applications in audio equipment. It was developed in the late 1940s as a direct replacement for the 6SL7 tube. The ECC83 quickly gained popularity due to its improved performance and ECC83. The ECC83 high impedance amplifier triode was designed specifically for audio use and has a high amplification factor of 100. Mullard describe the ECC83 as a high μ double triode, having separate cathodes, primarily intended for use as a resistance-coupled amplifier or phase inverter. This valve is still found in today's designs of hi ECC83S Vs. 12AX7: Insights. All in all, ECC83S differs from 12AX7 in two aspects: resistance (6 Ohms vs. 16 Ohms) and country of origin (British vs. America). Still, the differences prove insignificant in most of the cases so it's possible to use the tubes interchangeably. It is worth noting that quite a few modified versions of tubes exist |fjw| mul| svt| kjq| egr| ocg| qdq| xcj| khe| eqc| hko| wdx| daf| ucv| rvl| mwi| gfk| bht| sgb| sxc| vzz| fus| mle| npr| vhl| azy| xfs| bwq| mnv| nex| tju| fwy| rls| nkw| zut| dit| ibx| jyr| tep| bdy| vmh| bvz| ddr| bey| byt| csb| ieh| kon| bls| npm|
