Looking to warm up your Vaporizer? This is our Standard Retube Kit for the Fender Vaporizer Combo Amps. It uses two ECC83S's with one being current balanced for the phase inverter in V2. 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).
