Want something different? This is our Standard Retube Kit for the Diezel Herbert with Big Bottle 6CA7's. The preamp section uses six ECC83S's with one current balanced ECC83S for the phase inverter in V6.

The power tubes are a premium matched sextet of the JJ Electronic Big Bottle 6CA7's. The JJ 6CA7's have the harmonic complexity of an EL34 in the upper mids and highs and the deep low end of a 6L6. It's as close to mixing an EL34 with a 6L6 in one bottle as you can get. These tubes have round and natural sounding highs with thick low-mids.

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.
