12AU7

July 6, 2008 | Leave a Comment

The 12AU7 is a medium-mu twin triode miniature glass tube. In most circuits it is used as a class A amplifier per triode section. This tube has been, and still is, widely used in the preamplifier stages of high fidelity audio equipment, musical instrument amps, public address equipment, and broadcast equipment. It was used in so many different types of equipment that the vintage versions of this tube are still available without too much searching. Like their cousin, the 12AX7, the premium USA and West European brands are being hunted to extinction, but there are still bargains to be had in other vintage USA brands
