Looking to warm up your Atomic 16? This is our Standard Retube Kit for the Soldano Atomic 16 Heads and Combo Amps. It uses three 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).
