Want something different for your AC50CP? This is our Standard Retube Kit for the VOX AC50CPH and AC50CP2 with Big Bottle 6CA7's. The preamp section uses four ECC83S's with one being current balanced for the phase inverter in V4.

The power tubes are a premium matched pair 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 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.
