Want the smoothest richest tone you can get? This is our Gold Pin Option Retube Kit for the Benson Earhart 15 Head. It uses two Gold Pin ECC83S's for the front end, a GZ34 Rectifier and the default power tubes are a matched pair of the JJ EL84's. With the Customize option you can configure this kit to use the JJ EL844's which will drop the power output a couple decibels (ideal for players wanting decreased headroom/output).
