circuit for a low wattage amp

[Leevi]

I'm looking for circuit for a low wattage (1-2W) amp.
Would it work in a known SE amp (like Champ) if triode mode is
used instead of tetrode mode?

My suggestion would be to use a VVR with a single ended amp like a Champ or the SoLow Watt.  The VVR is only $30 and very easy to install.

That's fully true Tubenit. A VVR makes that possible, even dynamically.
Is it enough to use VVR only for the power tube?

Can there be used some other Mosfets if the current and voltage specs are fulfilled?

Leevi,

I have pretty limited knowledge of the VVR.  I think I've used them in 4 different amps with success but I always used Dana Hall's VVR which is inexpensive and easy to install.

You'll have to sign up to see the schematics, but I think there are numerous VVR schematics for single ended amps here:
