Want the smoothest richest tone you can get along with the KT77 sound? This is our Gold Pin Option Retube Kit for the Line 6 DT50 Heads and Combo amps and it contains two Gold Pin ECC83S's with one being current balanced for the phase inverter in V2. Less grit and a very lush tone!

The power tubes are a premium matched pair of the JJ Electronic KT77's. The JJ KT77's have the complex harmonics of EL34 type tubes with a really chunky low end and a big sizzling presence in the highs!

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 your amp is the head version and 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.

Doing what other tube resellers say "can't be done" since 1998
