Now was that all so hard, Brian? Did you peruse some websites to rethink
your internet theories? "LOL"


ROTFL! And after being completely humiliated in public because he
can't read a simple x-y graph, it now gets worse because he didn't
even go back to check his OWN graph:

He measured (or so he claims) his "1dB compression point" with an
unmodulated carrier. An unmodulated carrier is the same as PEP (as
well as CW). He doesn't even realize that his 129 watt "measurement"
is the very same "compression point" that he must use to rate SSB
power. So it's 129 watts PEP @ 1dB compression, not 322 watts!

So where did he get 322 watts? You know he didn't measure it or he
would have used the actual measurement the first time. Well, this
shouldn't come as a big suprise, but 322 watts is ALMOST EXACTLY 2dB
down from his original fish-story of 516 watts.

So much for his 'revised' power rating..... "LOL"!!!

Hey Brian.....

Since the transistors you are using are rated for a typical gain of
15.2dB, and you are using two of them, why is your amp rated for only
15dB instead of 18.2dB?

And at 18.2dB, if you shove in a typical 4 watt carrier from a CB,
doesn't that put your AM "RMS" output about 264 watts? (And your PEP
output at 1056 watts?)

Now assuming you have a magical amp that can achieve 55% efficiency
irrespective of the 35% collector efficiency of the transistor, when
you 100% modulate this 264 watt carrier (giving an AVERAGE power 396
watts), doesn't that mean you are going to be drawing 720 watts from
your power supply?

Just in case I missed something in 3rd-grade math you better check my
work he 720 watts / 15 volts = 48 amps. You also have a base-bias
current of 1 amp for each transistor, so 48 + 2 = 50 amps. Right?

But who uses a 15 volt power supply? Heck, we'll use the more common
automotive standard of 13.8 volts. So 720 / 13.8 = 52.2 amps, plus 2
amps = 54.2 amps.

HOLD ON A SEC.... Your amp only has a 30 amp fuse!!!

So after I get this all hooked up, wired directly to my battery and
everything, plug in my favorite little 4-watt CB, this amp is going to
blow a fuse every time I yell "A-U-D-I-O" into the mic.

Ok, I bypass the fuse and switch my CB on SSB with 12 watts PEP.
What's going to melt first -- the transistors or the power leads?

And you call this a "High Reliability Design"....."LOL"!!!

Because I attenutated the input, which gives the amp an overall gain of 15dB.


Well that doesn't make sense -- why use two transistors in an amp that
can be built with one? Aren't you the one that's always worried about
it being too expensive?

You are a real idiot if you don't know about slo-blow fuses.


I took that into account, Pouting Brian. That's why I calculated
AVERAGE power and not PEAK (PEP) power, just like it was outlined in
your favorite educational website.


Ok, I bypass the fuse and switch my CB on SSB with 12 watts PEP.

Your brain, but it melted a long time ago.


Good comeback, Pouting Brian..... I feel like I have been dissed by
the best...."LOL"!!!


And you call this a "High Reliability Design"....."LOL"!!!

Where's your amp, Frank?


That's what it all boils down to with you, isn't it?

You get up on the stage and sing like a rutting moose. When you are
done, the audience stops grimmacing and takes their fingers out of
their ears, and they begin their criticism. You can't take it so you
try to turn your lack of ability onto them by saying, "Let's hear YOU
sing." A classic 'sour grapes' response.

You built an amp without any engineering ability and it shows. If you
don't like the criticism, get off the stage. Otherwise, get ready for
the rotten tomatos because there are plenty more things I can pick
apart about your amp from your spec sheet..... for example, did you
know that total harmonic distortion can be calculated from an amp's
nonlinear response? And guess what: you posted the curve!

So get ready for round 2....."LOL"!!!

Good business strategy, Brian -- if you don't say anything, you can't
be proven wrong or give further demonstrations of your incompetence.
The only problem is that the damage has been done, and your posts are

claims.

Looks like the squabble is between whether you want solid realistic
performance with duplicable and sustainable levels, or the more impressive
(to the technically naive) maximum deflection Dosy watts. Might be better
to continue making the same amp but with two different housings, say, keep
the current look of the Henry style, but issue more modest and accurate
claims for its specifications, then put the same innards in a flashy
chrome plated case with a buzzword name (turbo, dynamic, quantum etc) and
state the extreme conjecture specifications that you seem to be arguing
for now. From my experience with the sundry vagaries of the CB milieu, I'd
guess there to be a market segment for each model.
