Doubt that you could get 25 watts out of that radio even if you keyed up the mic next to a tornado warning siren.
Don't know why would anyone want to push the output final beyond what it is capable doing on a continuous level. It would only force it to fail if you did. Nope; they were designed for 20 watts. You can't spend $10 f you only have $5.
If it has the MOSFET final in it and you made some particular changes to a couple of the caps in the output stage, you might milk up to 30 watts out of it. A non MOSFET final radio should do no more than 16 watts if done right.
The real value in a peak and tune is to be sure that modulation is matched to the mic you are going to use with it.
Or matched up to a linear amp. Its not about 'how many watts'; but how well the watts sound.
If you need more power, than a simple 100 watt linear with the radio's modulation and output matched up and adjusted by a tech will have the best results. Besides, its not the radio that gets out; it is the kid of antenna you use and just how well it has been optimized. I'd pick a mediocre radio with a great antenna over an expensive radio and a junk antenna - any day.

What in the world is a tech watt? Is it figured by some form of the P=I X V equation?
The final device is only capable of 20 watts max. But it is unwise to run it that high. Meters aren't that accurate, except for the Bird and only a select few others.
On AM mode, if the Bird tech can tell you that you are dead keying 4 watts with a peak power of 16 watts - that would be ideal. A 4:1 ratio of dead key to PEP (peak envelope power) with 100% modulation is correct.
On SSB, it will probably swing to 18 watts if he adjusted the ALC and the waveform looks is unclipped/undistorted on an oscilloscope. Most techs know this, or they don't stay in business too long . . .

I have a General Lee that keys 2 and swings to 10 watts on a Bird43. It swings to 35 watts on a Dosy and I have read posts where people are claiming 50-60 watts.
You need to change the term "Tech Watts" to "Bullshitting Cber Watts". :laugh:
The Bird isn't particularly accurate -- ±5% FS for average and ±8% FS for PEP (if the PEP circuitry is installed) isn't all that impressive.
What the Bird IS, is rugged. It still needs to be recalibrated every year; more often if you bang it around in the field.
It's no paragon of "accuracy", though.
