Tube exciter

[tiroth]

Anyone have any recommendations or places to start looking for a tube exciter? Of course a preamp design set to unity gain would accomplish this in some ways, but I'd be interested in comments on obtaining that vaunted "tube sound".

You could have a look at the Aphex Reflected Plate Amplifier patent( No.5450034) or the HiFi TubeHead on the Paia website
(www.paia.com). Both these devices are said to enhance tube sound.

Is the schematic for the RPA available if there is a patent number for it?
It looks like there is but the image wont load, has anyone seen it?

Optical, what you need to do is load a TIFF reader plug-in for your browser. The USPTO sites has links to several freeware readers. Then the image will be accessible, storable, and printable.

I always wondered why the USPTO didn't use Acrobat --

the TIFF reader is fine, however, I most of the time wind up ordering a hard copy -- they usually arrive in about 2 days here in NJ. You have to do this for most of the older patents anyway.

i'm rather confused as to what an exciter has to do with audio.

my exciter has a pretty face and brown eyes

no, that's an osculator !

here's an exciter:

makes it sound nice and full
well thats the idea anyway, it excites harmonics, result is similar to an eq..

thanks for the info on the TIFF plugin, i didnt know that, i figured it would let you download the file all the same..

jack, do you have a higher res image of the schem? looks interesting...

The expression exciter originates from RF technology where you use nonlinear circuits in order to generate integer multiples of a given frequency. That's what might have caused Colt's confusion.

The AURAL exciter also generates harmonics and lets the operator add those according to taste.

The outcome is quite astounding althogh it is just some sort of psychoacoustic cheating. It is definitely not HIFI if the meaning of this expression is taken seriously.
But it may help to add some warmth. It is best used for single instruments or voices; r the whole mix it should be avoided (depending on what you want to achieve of course).
