Marshall 100 Watt MKII JMP & 800 Series EL34 Amps Standard Retube

Product Details

This is the Standard Retube Kit for the Marshall 100 Watt Mark II JMP and 800 series amps with EL34's. The preamp section uses three ECC83S's with one balanced for the phase inverter in V3. The default power tubes are the JJ Electronic E34L’s but you can configure this kit to use the JJ EL34II's, EL34’s, KT77’s or Big Bottle 6CA7’s by clicking on the "Customize" button.

The Balanced ECC83S is located closest to the power tubes in V3.

Combo amps are very hard on tubes because of vibrations which can cause tube rattle with any brand of tube. If your amp is the combo version and you play by yourself in a quiet environment or record with your amp you may want to consider using the EuroDamper tube damper rings for the power tubes. These are available in the "Related Products” tab as a set of two. These will greatly decrease tube rattle.

These are all adjustable bias amps and all you need to check and adjust the bias is a bias probe and a Multimeter, or our all-in-one Eurotubes "Pro One" bias probe that reads both the plate current and the plate voltage simultaneously. You can find all these under the Related Products Tab.

You can use the "Generic Bias Video" we made using a Marshall 800 for reference.

The video below explains the difference between bias probe types.
