Custom Kit

Power-Tubes

Any of the power tubes listed below are compatible with your amp. 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. These amps are fixed bias with no adjustment. 6L6GC's or 5881's are your only choices for the quad of power tubes, however you can choose from matched pairs of EL34's, EL34II's, E34L's, KT77's and Big Bottle 6CA7's to run with the quad of 6L6GC's or 5881's. Please click on the “More Details” button for an explanation of the tonal differences. We left the "Quantity Field" active for those of you who may want a couple different types of power tubes to experiment with.

V3 is the second and third stage for channels three and four, here you can again increase or decrease the gain or smooth it out with a Gold Pin tube. The only tubes we stay away from in V3 are the long plate tubes which are more prone to feeding back in the lead position.

EuroDamper Tube Damper Rings

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. If your amp is the combo version then please let us know in the comments section. All Combo amp Retube Kits are shipped with the Eurotubes Double Mica 6L6GC’s at no extra charge. JJ Electronic started building us a proprietary version of their 6L6GC (the 6L6GC-DM) in 2005 with extra layers of mica. This reinforces the plate structure and all but eliminates tube rattle symptoms. For all other tubes such as, 6V6S’s, EL34’s, KT77's, 6CA7's and E34L’s, we recommend using our EuroDamper rings. These are 5.00 each.
