Diezel Herbert Gold Pin Option JJ Retube(TM) Kit with KT88's, KT66's and KT77's

Here at Eurotubes we love integrating different power tubes and the Herbert is made for this! This is our all "KT" Gold Pin Option Retube Kit for the Diezel Herbert with KT88's, KT66's and KT77's! It contains six Gold Pin ECC83S's with one being current balanced for the phase inverter in V6. Less grit and a very lush tone!

The power tubes are premium matched pairs of the JJ Electronic KT88's, KT66's and KT77's. The KT77's provide the high end sizzle and the combination of the KT66's and KT77's together make for an extreme harmonically complex mid. The KT88's add a thunderous low end to the mix and further fatten up the mids. An amazing combination!

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 mount using the same screws as the stock retainers.

Unlike other tube venders who charge for low noise tubes, all our tubes meet rigorous tests for low noise, microphonics and nine additional tests.

If you want all the power and fidelity to get from your amp to your speakers then check out our custom made 10 Gauge speaker cables in our Reverb storefront. These cables are the largest cables made and leave no frequency unheard!

The video below shows both our preamp tube testing and power tube matching procedures here at Eurotubes which are second to none. We may not be the cheapest, but we are arguably the best.
