Audio Tubes
NOS NIB

Buyer gets both of the tubes in the photos.  These tubes were tested in my Military Hickok Cardmatic to make sure these were perfect.   All the tests were excellent.  Both of these tubes were made in the USA, by RCA, in 1968.  These are the low noise, grey plate, halo getter version.  These tubes are the premium Tektronix laboratory tested tubes.
These are getting scarce and are a high end tube used by most of the professionals.   Great for any audio amplifier, especially guitar amps.  These tubes are what audiophile enthusiasts are looking for.  The tubes will come in their original Tektronix 12BY7A boxes, as shown.  These tubes are NOS (New Old Stock).

RCA codes: BV (1968)


Test results:  92 (12696 GM) & 92 (12696 GM), where a minimum good is 50 (6900 GM).  These are an exact matched pair, with very high test readings.
