Mesa Boogie Express 5-50 Standard Option JJ Retube(TM) Kit

This is the Standard Retube Kit for the Mesa Express 5-50 and 5-50 Plus amps. The preamp section uses five ECC83S's with one current balanced ECC83S for the phase inverter in V4. The power tubes are a premium matched pair of the JJ Electronic 6L6GC's.

If your amp is a Combo then message us at the time of purchase and we will make sure you get the Eurotubes exclusive 6L6GC-DM "Double Mica" power tubes to reduce tube rattle.

All our Mesa Retube Kits include power tubes that are hand selected to run perfectly in Mesa amps. We have extensive hands-on experience measuring the fixed bias points in these amps and what grade of tubes will achieve optimal performance.

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.
