The 12AX7 commonly identified in Europe with the acronym ECC83 is a "dual-triode" miniature. His first project dates back to 1947 and was marketed a year later. It is the successor of the 6SL7's family, a tube created for AUDIO applications, very popular especially in pre-amplification for HI-FI sets and musical instruments, especially in the entry and mid-level stages. The 12AX7 has high gain (Mu 100 µ) and low anode current, ideal for low level audio voltage amplification.
