I´m trying to wrap my head around these hybrid amps.
I´ve got a few simple questions that i don´t seem to find any simple answer on.
Could you do a voltage divider from the valve preamp and use a lm3886 as a "output" tube?
Or if i would use fet´s as a output tube how high voltage can i pass thru the gate? And how much gain could i expect?
i´m thinking preamp tube---->PI---->two lm3886(one for - and one for + phase)?
I´m kind of a thinkerer and i´m starting up a life time project. As you understand my knowledge about amps is fairly basic especially SS amp´s.
edit to add: Were talking about a guitar amp.

You don't really need a PI, the power amp is going to be push pull already. the chip amps like the 3886 are, or the TDA7293, or even a plain old discrete transistor amp. The phase splitting function is already a part of those. Feed it the signal as is.
A signal is a signal, each stage that gets one has no idea where it came from. I can play a guitar into an amp, or I can record my guitar and play it back into an amp. The amp won;t know or care. In fact, that is a studio trick so they can play the exact same guitar performance through a different amp to get a different sound.
So you want to make a tube preamp? Go ahead. Check the level of signal leaving your preamp and adjust it to suit the next stage, your power amp.
