Looking for a smoother overall sound with a less aggressive overdriven tone? This is our Gold Pin Option Retube Kit for the Benson Nathan Jr Combo Amp. It uses one Gold pin ECC83S and one Gold Pin ECC832 for the front end, along with a single Double Mica JJ 6V6S for power. These are a special version of the JJ 6V6S's made exclusively for Eurotubes to greatly decrease tube rattle in combo amps.
