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?


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?


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.


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.
What's going to melt first -- the transistors or the power leads?


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"!!!
