This is our Standard Retube kit for the Fender EVH 5150 III. It uses eight ECC83S's with one being current balanced for the phase inverter in V8. The default power tubes are a matched quad of the JJ 6L6GC's but you can also run a quad of 5881's, KT66's or an Integrated Quad consisting of a pair of KT66's and 6L6GC's matched to run together with the KT66's in the outside two sockets. You can customize the kit by clicking the "Customize" button.
These amps are adjustable and you can use the factory test points and a Multimeter or you can use a bias probe with a Multimeter which is more accurate, or you can use our All-in-one "Pro One" bias probe which reads the plate voltage and the plate current simultaneously.
You can use our Generic Bias Video for reference. The video below explains the difference between bias probe types.
