NOS-Chinese 12AX7
Brand new unused new old stock triple mica 1980's and 90's Chinese 12AX7's with the dimpled square foil getter. Mesa Boogie, Marshall and Peavey used these tubes back then. These test high grade so should probably be avoided in the most sensitive V1 spot, but are fine for V2 and down the line. Limited supply of these out of production tubes from the closed Beijing tube factory.
