Greetings from Saskatchewan . Closing down my studio and you have come across a great Aphex Aural Exciters that is a Type B. Which are real hard to find and sound real good. I have this Type B  for sale and is in great shape and works as it should. Please note on older units they  may need their pots and/or other controls internally sprayed or cleaned.As  I have not used this in sometime as my main room was closed years ago.  Please save your insults and low ball offers for friends; he he I am too old as I am 60 now and Covid has killed my business thus I am selling gear and going to get a job. This does not mean I am giving it away he he.
Please no insulting offers as I am too old to deal with that. Will not ship to Mexico as have had too many issues and bad experiences with that area . Sorry for the crappy pictures  used my iPad instead of my phone. 

We are in CANADA and the buyer is responsible for all freight duty , customs brokerage and taxes. Just want to be clear as  I  get lot of email about freight and " oh I did not know you were in Canada" I though Saskatchewan was part of Alaska ,lol"

Feel free to put in an offer on this great used studio piece of cool electronics .

We are good people  just trying to make a living and we are not a big box store.

Canadian Buyers Must pay GST .

Will just charge you what freight is to your area as these guys are heavy and freight is just an estimate . So please do not freak out.

Here is some info on the Type B Aphex Aural Exciter.

In 1975 the Aphex Aural Exciter was unleashed upon an unsuspecting studio, broadcast and film industry. Most engineers and producers found that the device gave increased presence, clarity, and a greater perception of 'loudness' without increasing level.

In those days, it was not possible to buy such a unit but the device had to be rented according to the amount of time it was used on each track. A black sealed box with some knobs on was delivered to the studio and there was no way for inquisitive engineers to prise it open and peer at its insides.

In the past few years there have been one or two similar devices on the market at a cost much less than the original, but now Aphex Systems Limited have introduced their Type B low-cost version of the original Exciter.

What It Does

The Aphex works on the principle of generating, within its circuits, fourth and fifth harmonics of the input signal which are mixed in with the input signal at the output. It is thought by the psycho-acoustic researchers that these harmonics are the minute cues which our subconscious minds interpret as 'presence' or 'realness'. It is claimed that it is these missing cues that the Aphex Aural Exciter re-creates and adds back to the main signal to change the way in which we perceive what we hear. Other conventional types of processors such as equalisers or reverberation, enhance those parts of the signal that are left when these cues are masked by the recording process. The Aphex Aural Exciter replaces these masked sounds.

Because the harmonics generated are derived from the main signal, they are musically related. The harmonic structure of each sound or instrument, therefore, is strengthened, allowing it to stand out from others. This manifests itself in a perceived increase in clarity or treble boost without giving any measurable increase in level.

How It Does It

The main signal going into the Aphex Aural Exciter passes through unchanged. All the processing is done in an outside loop (called a side-chain) and this processed signal is added in very small amounts to the main signal.

Before the signal in the side-chain reaches the harmonic generator, it goes through a tuneable high-pass filter which removes any unwanted low frequency information. The level of this signal is then metered by a multi-coloured LED before it goes to the harmonic generator. The generated harmonics are then added in with the original signal, and the mix varied by the Mix control.
