Want maximum gain to go with the classic 6L6GC sound? This is our High Gain Option Retube Kit for the B52 AT-212. The kit includes a GZ34 rectifier tube and the preamp section uses one ECC81 to replace the 12AT7, a standard ECC83S for V11 and five Handpicked High gain ECC83S's with one balanced for the phase inverter in V5.

The power tubes are a premium matched quad of the JJ Electronic 6L6GC's. These tubes have big lows, smooth mids and crystalline highs. What sets them apart is their low end clarity, mid-range detail and very clear highs without being overbearing or harsh.  

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.
