Want a very smooth and rich tone with less grit? This is our Gold Pin Option Retube Kit for the Line 6 DT25 Heads and Combo Amps. It uses a current balanced Gold Pin ECC83S for the phase inverter 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).
