12bh7a retifier


Greetings to all,

I saw a ad somewhere that said the 12bh7a was the same as a 6SN7 tube in a nine pin configuration. Anyone agree with this. I use the 12b in my N.E.W P3 preamp. Enjoy the music.

Rrog thanks for the info. I suppose then the 12au7 tubes are for the input part of the circuit. I may get a hold of Dennis at Cary for additional info.
12BH7 is not a rectifier. It is in the circuit because it serves as an output tube in your preamp.
Jax2 if the 12b is not a rectifier then what is it doing in the circuit? If I'm not mistaken the P3 does not have SS rectification.
Neither the 12bh7 nor the 6SN7 tubes are rectifiers. The 12bh7 is a 12volt tube and the 6SN7 is 6 volts. They are not compatible in the same circuit.
