Diezel Herbert High Gain Option

Product Details

Want all the gain you can get? This is the High Gain Option Retube Kit for the Diezel Herbert. The preamp section uses two standard ECC83S's in V4 and V5 along with four handpicked High Gain ECC83S's with one balanced for the phase inverter in V6. The default power tubes are three matched pairs of the JJ Electronic KT77's but you can configure the kit to use three different pairs of almost any octal power tubes including the JJ E34L's, EL34II's, EL34’s, Big Bottle 6CA7’s, JJ 5881's, 6550's, KT66's or KT88's by clicking on the "Customize" button! You can even run a pair of KT77's, KT66's and KT88's! The possibilities are endless.

The Balanced High Gain ECC83S is located in V6 which is located farthest from the input jack. The two standard ECC83S's are located in V4 and V5.

If you choose to use the KT66's, 6550's or KT88's and your amp has the "Bear Trap" style tube retainers you may want to swap these out for the "Spring and Cap" style retainers. These are 5.00 a pair and mount using the same screws as the stock retainers. These are also available under the "Related Products" tab as pairs.

These are adjustable bias amps and if you use the Diezel method of removing fuses to measure bias all you need is a Multimeter. This method is a bit tedious, it's much easier and convenient to use a bias probe and a Multimeter or our all-in-one "Pro One" bias probe that reads both the plate current and the plate voltage simultaneously. You can find all these under the Related Products Tab.

You can use our Generic Bias Video for reference.

The video below explains the difference between bias probe types.
