But you can dream, right?

I thought you were going to show me how to design a amp that was
superior to mine... and was a product that was easily manufactured,
repeatable, reliable, and profitable. Business-101 Frank. From what I
can see of your design concept so far... you should reply... "none of
the above"... LOL


Repeatable -- Not only am I making the final design public, the entire
process is going to be public domain. You, OTOH, won't even release
your schematic for fear of constructive criticism.

Reliable -- In case you haven't been paying attention, the fundamental
concept of the design is longevity. These amps are going to be around
and working long after you and your amps are dead and buried.

Profitable -- I have saved the best for last. The -best- thing about a
modular design is that it is perfectly LEGAL!!!. I can manufacture and
market the chassis and modules independently under the premise that no
component, in and of itself, constitutes an amplifier. The only way
the government can touch this is if they outlaw every aspect of hobby
electronics and the sale of each and every component, which we all
know isn't going to happen (unless Bush declares a national emergency
right after the 2008 election, refuses to give up his office, and
installs a Republican dictatorship). There isn't one business-person
on the planet that wouldn't invest in a business that can open up an
entire market that was previously illegal. That, my friend, is called
"profitable".

But you go ahead and continue your work on your diminutive little amp,
knowing that your market is limited in both scope and time. Feel free
to waste your time on a product that will soon be without a market.
The only thing you have going for you is the price.... but then again,
have you done any market research lately? Do you know what people will
pay for a decent amp? Probably not. But I have.

So now that the cat's out of the bag, how hard are you going to fight
this? Or would you rather buy into it and make a ****load of money?
Feel free to email me with your answer.

**Your statement here has nothing to do with having a repeatable
design.**

**This is all talk right now. The fact that you will be using
components such as connectors for board-to-board interfacing does not
lend itself to high reliability.**

**Again, nothing but talk and very premature... you have no design yet
to base any profitability claims.**

There is a problem here with 'profit'.
I just had a look at where I bought some other stuff, what amplifiers
here go for:
100W MOSFET 42 Euro and 86 cent ( 54 $ and 44 cent).
500W 242 Euro and 93 cent (308 $ and 58 cent).
1000W 660 Euro and 15 cent (838 $ and 55 cent).

Will indeed be hard to make any $$$$ on 100W amps.
Not so different in the US I think, 1700W 650$:
http://www.amateurlinearamplifiers.c...ce=hotproducts

500W 329$
http://www.amateurlinearamplifiers.c...ce=hotproducts


I cannot make 100W for 54$, and I cannot make 1700W for 650$......
You have to count the hours too.

Telstar has been at it now for years.....
At 4$ profit per amplifier you'd have to sell zillions.
:-)

OTOH as a learning exercise making them was great.
Just that I stopped when they were at in the street with the radio car to
arrest me, spotted them just in time.... OK maybe I had some harmonics...
and one licensed amateur was upset.... when he did see me with those big
toobes.
'If I hear you I will turn you in'.
He was later overrun by a car IIRC.
It somehow strengthened my faith in God.
But that is all of the past, and not on 27MHz.

Honestly.
Damn are we honest today.

Frank, just how much do you think this amp is going to cost? Sounds
like It's going to be out of this world with all the stuff you are
talking about...

50 volt power supplies are very cheap to build. if you have the right
connection with parts suppliers less than $10.or less figure $ 20 max. Money
spent here will also save money elsewhere in the amp. Its a pain in the but
to build a decent amp that works of of 12 volts. 50 and 100 volt amps are
easy.

When it comes to designing a good amp there is no reason to reinvent the
wheel. There is better stuff out there to use than there was 30 years ago
and its much cheaper now than ever but for the most part amp design hasnt
changed much. For what improvement have been made I see few amp builders
taking advantage of them, the same crap designs that have been around for 30
years Most people who can get an amp to work at all think they have done it
RIGHT. I see people who have tried to get 10KW out of a 12volt amp and my
hat's off to those that pulled it off but this is still some **** poor
engineering
