This is our High Gain Option Retube kit for the Fender EVH 5150 III 50W Stealth EL34. It uses five handpicked High Gain ECC83S's for V1 thru V5, a standard ECC83S for V6 and a current balanced ECC83S for the phase inverter in V9. The default power tubes are a matched pair of the JJ E34L's but you can also run a pair of EL34's, EL34II's, 6CA7's, or KT77's. 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.
