GE NOS USA 12BH7A MATCHED PAIR CLASSIC USED BY MCINTOSH AND OTHERS IN THE GOLDEN DAYS OF AUDIO This listing is for (2) brand new, old stock factory fresh GE 12BH7A as a matched pair. Tubes are matched for gm on a Amplitrex AT-1000 tester. We tried these in an MC-225 and a pair of MC-30s, and the amplifiers measured better and sounded better. NO SNAKE OIL TREATMENTS HERE. STAY AWAY FROM THAT STUFF UNLESS YOU WANT YOUT TUBE GEAR TO SOUND LIKE 1970s TRANSISTOR GEAR! This is a well constructed 12BH7A, that tests and sounds excellent. They test consistently with very high gm readings. A perfect differential driver tube. This is a requirement for the driver differential amplifier in the McIntosh and other amplifiers.
