Want all the gain you can get? This is our High Gain Retube Kit and it contains four handpicked high gain ECC83S's for V1 thru V4, a standard ECC83S for V5 and a balanced ECC83S for the phase inverter in V6. The default power tubes are a matched pair of the JJ 6L6GC’s but you can configure this kit to use the JJ 5881’s by clicking on the "Customize" button! If your DC5 is a combo amp and you choose to go with the 6L6GC's then please let us know in the comments section and we will ship your kit with the special Double Mica 6L6GC’s which will greatly reduce any tube rattle.
