From: "Morgans"

I had heard a few years back that audio aficionados had been going back to
some
tube technology, and you are the first specific instance that I had heard of.


Tubes never really went away in the area of music CREATION.
They tend to emphasize the uneven overtones (5ths and maj. 3rds) and give
sound a certain "warmth".
My "amp of choice" for my guitars is still an old, 1970 vintage Fender Quad Reverb.
An added benefit is that when I fire it up in the winter......it heats my house.

I always liked my Heathkit Amp, until the sound of caps gassing up, (then
blowing over/open, or whatever you want to call it) was almost as frequent as
the sound of clear music.


Hey! I built one of those.
It was still working when I sold it in the late 70's.

Ok you guys... This is bringing back alot of wonderful memories of my
early years. I built some heathkit stuff, bought them from Olson
electronics in Miami Fla.. Ahhh, the smell of solder and the feeling
one gets when you plug it in for the first time and it doesn't smoke
or trip the breaker,,, Actually they were those screw in fuses back
then... Seems to me I killed more of the green fuses then the red
ones, but I digress......... I also agree on the fine sound of the
fender amp. I had a Strat and a bandmaster amp in another life and
those days were a great time, and the beginning of my hearing
loss. :)). Thanks for reminding me....

Now back to your regular scheduled programming. !!!!!!!!!!!!

Ben.

If you spent as much time trying to _DO_ your project as you are
spending _TALKING_ about it, you'd be halfway to failure by now.


But, if I'm wrong, I'll offer you a little advice.
Success will get every opponent to shut up.
And 3/4 of them will claim that they had faith in you, all along.


Sounds fair.


I loaded SolidWorks onto laptop yesterday. As mentioned, I will report
either success or failure, whichever occurs.


Do hurry, I'll be holding my breath.

Can't you at least post a drawing or something before then?

Personally I think what you're really needing is anti-grav drive.
There was a German guy working on the theory of it. Burkhard Heim was
his name. He died, though, before completing his work. But here's a
start:

http://www.rialian.com/rnboyd/burkhard-heim.htm

Now you have to be able to read German and most physicists don't
really grasp his mathematics and system of physics, but you'd probably
make pretty good progress once you had the anti-grav drive part down
pat. The rest should be a piece of cake.

Anyway the American Institute of Aeronautics and Astronautics awarded
a prize for a paper on the concept:

http://space.newscientist.com/articl...yperspace.html

New Scientist mentions Sandia Labs and the US Military looking into it
though, so you may simply be too late (alas!).

Still, there may be a homebuilt market for similar technology, so your
efforts might not be entirely wasted.

THe above type of concept is what we would need in order to fly to other
planets and the stars on a routine basis. It certainly piques the
imagination!

I will as soon as I figure out a configuration that works. The ones I
have conceived so far might have power-output problems, even for one-
seat aircraft. There is a lot of math, with cyclic dependendies that
has to be worked out.

My still-in-thought idea is far less exotic. Everything is based
Newtonian physics.

It's a PGP signature. If you have a PGP decoder and download his
public key it's used to prove the message came from who it says it did
since nobody else's private key will encrypt to the appropriate string
above. Eliminates people forging posts since they either won't post
with a PGP key (rules the post in as a forgery if the real user always
posts a key), or the string won't validate against the real user's
public key.

Except for one minor detail: since the guy hides behind an anonymizer,
there's no information gained from the fact that the message passes the
signature test, since all it proves is that the same anonymous coward posted
each one.
