Does anyone know what the color codes and the "number" on Mesa power tubes mean? For instance the ones in my MkIII are "Gray 14". My MkIV has "Yellow 37" and I saw some on eBay that are "Green 10".
Are these used on other brands as well?
EDIT: Mods- feel free to move this thread to the Tubes section... didn't see that !
