Looking to freshen up your tone? This is our OEM Retube Kit for the Benson Earhart 15 Head. It uses two JJ ECC83S's for the front end, a JJ 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).
