Want a really rich and smooth tone with less grit? This is our Gold Pin Option Retube Kit for the Diamond Positron Amps. It uses three Gold Pin ECC83S's with one being current balanced for the phase inverter in V3. 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).
