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.
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.
12AX7's and 6L6's.
It's a thermionic valve/electron tube with *two* triodes in the one envelope. Examples: 3A5, 6J6, 6SN7/6SL7, 12AU7/12AX7, ECC32, ECC82.
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.
What is a substitute for saltine crackers??? Is there even a substitute it???
Both are correct, you can say substitute for or substitute with.
I used applesauce as a substitute for oil in the recipe to make it healthier.
There is not a substitute for treacle. This has to do with cooking.
There is no substitute.
scapes substitute
Yes, both "Substitute Teacher" and "Substitute Paraprofessional" should be capitalized when referring to specific roles or job titles.
Substitute could be an adjective or a noun. For example, "The substitute teacher" uses subtitute to describe what kind of teacher. "The substitute passed out the homework" uses substitute as a noun by itself
