Ray Tubes 12AX7 Select vacuum tube

The 12AX7 vacuum tube was introduced in 1947 as a replacement for the earlier 6SL7 family of dual triodes, all of which were used extensively in audio applications. As one of a handful of small signal tubes that have remained in production since their first use, the 12AX7 is commonly found in the pre-amp stage of tube amplifiers and is especially associated with the emerging electric guitar sound of the 1950s.
