Looking for all the gain you can get from your King Snake Combo? This is our High Gain Option Retube Kit™ and it contains a standard ECC83S for the verb in V4 along with four Handpicked High Gain ECC83S's for V1 thru V3 and a balanced High Gain ECC83S for the phase inverter in V5. 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!
We ship this kit with the special Double Mica 6L6GC's which will greatly reduce any tube rattle. If you choose to use the JJ 5881's then we recommend using our tube Damper rings for these tubes.
