LIMITED STOCK. ACT QUICKLY. THESE WILL SELL FAST. 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. Purchasing a tube without matched sections in these amplifiers is a waste of money and will cause increased distortion. CTech Electronics stands behind all of its products and services.

Also it can be used as an Output tube, producing Maximum 5 Watt Single Ended. It uses AVVTs unique Open filament structure, resulting in extreme linearity, also at high output voltage. Features: AVVT’s parallel ribbon filaments with 16 flat surfaces, for more linearity ; two large getters ; white Nickel plates ; c37 Shaped Glass ; Anti-microphonic Suspensions in tube top ; Hard Metal filaments which can never break ; Ceramic UX4 Socket with Gold Plated pins. Note: the “Open Filament Structure” means, the filament and the grid are longer than the anode, and stick out on both ends for about 5…8mm. The not fully warm ends of the filaments do not have a very good function, and cause distortion. This tube doesn’t use this part of the filaments. Emitted electrons from the cold ends, will bypass the anode, and land on the glass. At maximum Power this may cause fluorescent, blue glow on the tube glass inside. Note also “Hard-metal filaments” are operated at much higher temperature than normal tubes. This tube will glow bright orange, instead of the dark orange color of nickel filament tubes.
