Hi, I'm noob in the use of LTSpice, so I'm unsure about the correct sintaxis of directives, to have the program giving correct results
What I'm looking for is to see the armonic decay of a little tube amp, while
drove it  at 1W output, and the way it's affected by the presence/ absence of an NFB loop.
The *asc file is at the Files folder , under the name EL84/EL84
