Mesa Boogie Studio 22 "Low Output" Standard Option JJ Retube(TM) Kit

This is our "Low Output" Standard Retube Kit for the Mesa Studio 22. The preamp section uses five ECC83S's with one current balanced ECC83S for the phase inverter in V5. The power tubes are a premium matched pair of the JJ Electronic EL844's.

This Retube Kit is plug and play with no bias worries. These are completely different tubes than the stock tubes your amp came with. The JJ EL844's are a proprietary tube that JJ Electronic built at the request of Eurotubes.

The dissipation of the JJ EL844 is 25% less than a standard EL84 so using the EL844's will reduce the power a little in your amp.

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.
