12BH7A Push-Pull amplifier |
 |
||
It is a tube so can make parallel push-pull amplifier easily , and was popular as small output. The output is 5W*5W. This is one of my favorite amplifier.
I made the amplifier for the first time using this tube in 1968. I was a junior high school student at the time. I think that the photo amplifier is remade in 1972. Circuit diagram |
