Looking for a really smooth and rich tone with less grit and the powerful aggressive JJ E34L sound? This is our Gold Pin Option Retube Kit for the VOX AC50CPH and AC50CP2. This kit includes four Gold Pin ECC83S's with one being current balanced for the phase inverter in V4.

The power tubes are a premium matched pair of the JJ E34L's. The E34L's provide a deeper low end and are more aggressive and punchy than a standard EL34. The E34L is tighter with slightly more headroom and power with a more aggressive crunch, a very articulate British tone!

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.
