Guys
There are possibly 15,000+ posts devoted to the F5 and Turbo, I simply haven't the time to go through them all.
Does anyone have any definitive measurements please ? Especially power into 8 & 4 ohms and pulsed power into 2 & 1 ohms ?
The 2012 pdf says with modification you can get 38A into 0.1 ohm, way more than I need !
But even measurements of a standard F5 would be good. I can't find a copy of the Audio Express either ?
Thanks
Dave

how about rephrasing the question, and perhaps telling us what your application for the amp may be?
As AndrewT said, you can make the F5T suit many different variations of power requirements, its just a matter of implementation. This is a DIY project, and you can tune the outcome to your liking within restraints.

One can not exceed the SOA of the output devices.
That's the place to start.
Armed with this information you can determine how many devices of what type using what rail voltages and what bias point are required to produce what power into a given load.
As far as measuring distortion, that is another question.
Perhaps you might ask that one if ur interested.

Well chaps, my question is quite short and clear as above.
Am I seriously to believe no one has ever measured this on any F5 amplifier ?

I would like the answer to my question please ? But if no one can provide it, I'll move on as I can see some friction developing here.

Dave,
There are distortion graphs on p.15 and 16 of the F5 manual:
http://firstwatt.com/pdf/prod_f5_man.pdf
For a standard F5 at 1KHz, it looks about 25W into 8R, 40W into 4R and
50W into 2R.
