Mesa boogie / Mesa 6L6GC STR-430The Mesa STR-430 is the same valve as the Sovtek 6L6WXT plus and 6L6GC-Electro Harmonix.
The Sovtek 6L6GC- EH is the impoved version of the Sovtek 6L6WXT plus.The the EH version is more linear and handles higher plate
better but is basically the same valve.
In my experience in our recent tests both the winged C Svetlana 6L6GC and Harma 6L6GC-STR offer sonic improvements over the Sovtek items and these would be my choice. If you want the same item as this then order the Sovtek/Electro Harmonix 6L6GC-EH we have these is selected sets for Mesa boogie.
PLEASE NOTE we do not stock this valve,
