Want a very rich and smooth tone with less grit? This is our Gold pin Option Retube Kit for the Genz Benz El Diablo 100. The preamp section uses three Gold Pin ECC83S's and the default power tubes are a matched quad of the JJ Electronic E34L’s but you can configure this kit to use the JJ EL34II's, EL34’s, KT77’s, Big Bottle 6CA7’s, 5881's or the JJ 6L6GC's by clicking on the "Customize" button.
These are adjustable bias amps and all you need to check and adjust the bias is a Multimeter.
