The late 1950s-early 1960s 12AU7A tubes in this precisely matched pair were made by RCA and labeled for Hammond or Conn organs. They have clear tops, side getters, and ribbed gray plates. The condition of the red labels varies (see photo).
Both tubes test as new with balanced sections and very low noise. They are matched for both current draw (mA) and transconductance (Gm). Tubes ship in new white boxes.
These tubes are sold as a matched pair. Photo is a sample from the lot. Singles, when available, are listed as Item 26.
