Do you like fat mids and little extra high end sparkle? This is our ECC803S V1 Option Retube Kit. It contains a JJ ECC803S for V1 for a little lower gain with big thick mids and a little more sparkle in the highs along with four standard ECC83S's for V2 thru V5 and a balanced ECC83S for the phase inverter in V6. The default power tubes are a matched quad 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.
