Looking for a thick vintage tone to go with the fat sound of the JJ EL34 II's? This is our ECC803S V1 Option Retube Kit for the Carvin X100B with the JJ EL34 II's. It contains a premium matched quad of the JJ Electronic EL34 II's for power along with a Long Plate JJ ECC803S for V1 which has big thick mids and a little more sparkle in the highs, a standard ECC83S for V2 and a current balanced ECC83S for the phase inverter in V3. Thick and fat!

Using a well-balanced preamp tube in the phase inverter position will eliminate any phase cancellation allowing all notes to ring out and sustain well.

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.
