Mesa Boogie Express 5-50 Standard Option JJ Retube(TM) Kit with 5881's

This is the Standard Retube Kit for the Mesa Express 5-50 and 5-50 Plus amps with 5881's. 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 5881's. The JJ 5881's are a Classic 23 watt 5881 in a traditional stubby bottle. "Jangle" for days and a very warm full tone. Right in-between the JJ 6L6GC and the JJ 6V6S in power. If you're looking for a little earlier breakup these are it.

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.

If your amp is a Combo then you may want to look at our Large EuroDamper Tube Damper Rings for the power tubes. These will greatly reduce tube rattle in Combo amps

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.
