Hello sergiog
(sorry my autocorrection put it wrong)
I just read this post of yours. Having the same issue, I wanted to ask if you followed this path and did build a "2/3F4"?
How di it work?
How did you do it?
thank you!

BUILD!
Everything but the chassis is here. (probably 1 or 2 parts glitches and Salas' B1 waiting for me)
...
At the moment, I'm trying to work out (like, calculate
) the heat-sink-requirements. Looking for power-dissipation per transistor etc etc...
6L6, I read that you use cardas quad eutectic. Do you use their Rosin Flux Paste too? Because I do, and it's quite messy...
Yes.

I like the Cardas Quad. I have not used their flux.
Heatsink requirement is easy - 4U deluxe chassis.
I've used their flux and while nice I don't think its needed for most applications. On top of that its a pain to clean the excess which can be a lot even when using a small dab. Been using the Cardas solder though for a few years and its great. I use it and along with kester solder
For this idea, why not a Mofo build with lower voltage? (I don't know what low power Mofo sounds or measures btw, just the first thing to jump in to my head.)
To get 7-8w max out of my F4, I adjusted B+, the primary (5k to 2.5k) and secondary connection (4k to 16k) of my 2a3 SE amp and drove it with that.

Nothing. Nothing speaks against building a Mofo. Quite the opposite. But only _after_ F4
