This is the Integrated Quad Standard Retube Kit for the Mesa Roadster and Trem-O-Verb amps. This Kit uses five standard JJ ECC83S's in V1 through V5 and a current balanced ECC83S in V6. For the power section the default power tube selection is an integrated quad with a matched pair of JJ 6L6GC's and a matched pair of the JJ KT66's. With the Customize option you can configure this kit to use a range of integrated quads including our classic KT66/KT88 and KT77/6V6 options. Just as we do with standard quads, we match all the Integrated quads for optimal bias in your amp.
If your amp is the combo version then please let us know in the comments section and we will ship your kit with the special Double Mica 6L6GC’s which will greatly reduce any tube rattle.
These amps are fixed bias with no adjustment. All power tube configurations are hand picked with grades that will run optimally in their respective modes. 6L6GC's, KT66's and KT88's are run in the 6L6 mode.EL34's, 6V6S's, E34L's, KT77's and 6CA7's are run in the EL34 mode.
