If you don't like much grit in your tone and you're after a very smooth and rich sound then this kit will do it. This is our Gold Pin Option Retube Kit for the Carr Mercury. It uses two Gold Pin ECC83S's to replace the 12AX7's along with a Gold Pin ECC81 for V2.

The power tube is a premium tested JJ Electronic KT77. 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.

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
