Want all the gain you can get? This is our High Gain Option Retube Kit for the Soldano Decatone. It uses a standard ECC83S in V4 along with four handpicked High Gain ECC83S's with one being current balanced 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 KT66's or even the JJ 5881's to drop the power output a couple decibels by clicking on the "Customize" button!
