This is our ECC803S V1 Option Retube Kit for the Carr Mercury. It contains a Long Plate ECC803S for V1, an ECC81 for V2 and an ECC83S for V3. The ECC803S Long Plate tubes have cool vintage vibe with a great high end sparkle and big warm mids!

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

Shipped and insured by Priority mail which is a 2 to 3 day delivery!
