In electrical circuitry, a 12az7 tube does what other tubes do; that is, control electrical current so as to produce desired results in electrical appliances such as radios and musical instrument amplifiers.
All those tubes are double triodes, but their characteristics differ. This means that any of them could possible substitute another, but that would depend on the characteristics of the circuit in question.
you can substitute them, meaning that it will function in a circuit that uses common dual triodes, but if your using it in some audio/instrument/microphone application it probably wont perform the way you want it to. It IS a medium gain dual triode and wont overdrive in a guitar amp the way a 12ax7 does (BTW thats why your amp came with 12ax7''s and not 12bh7's in it) . Also this is a general statement.
It's a thermionic valve/electron tube with *two* triodes in the one envelope. Examples: 3A5, 6J6, 6SN7/6SL7, 12AU7/12AX7, ECC32, ECC82.
No, cathodes are negative in an electrical circuit.
The current flowing in an electrical circuit.
The drawing of an electrical circuit is called a.............= schematic drawing.
The circuit trip in your electrical system could be caused by an overload of electrical devices on the circuit, a short circuit, or a ground fault.
No, an electrical approved switch is used to break an electrical circuit.
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.

The anode is positive in an electrical circuit.
Yes, the cathode is negative in an electrical circuit.
