This is a barely used Comp 3A with the revive audio modification plus the Kenetek Opto. In addition to the kenetek opto, the original Golden Age opto is included as you can see in the photos.

This unit sounds great but I'm moving to a new studio that is wired up with 500 series racks so I won't have space for this.

The warranty card is for the Kenetek Opto that is installed in the unit.

The Revive Mod Info:

Golden Age Comp3A Mod

On the GA Comp 3A we offer a wonderful circuit upgrade that CULLS its namesake and really brings out the Urei.

We put a lot of love into the mods on this one, as with all of our modifications, to squeeze out the maximum performance possible.

While the design sounds pretty good stock it really lacks low end, audio mojo and has a pretty high signal to noise ratio.

With the modifications they sound great on Bass, vocals, room mics and more and are really close to the original in terms of quality and character.

Once you hear it, you will be excited to put it anywhere you would want to put a Comp 3A, like vocals and Bass

On these we do a full circuit mod to get the circuit as close as possible to the original and install a custom set of Cinemag and Altran transformers for warm audio and transformer mojo that is lacking in the Chinese Reproductions.

We also offer an optional Kenetek T4b Opto Cell as an option which is the closest to the original Opto Cell that has ever been made.

While there is only a small amount to be gained in compression knee character with the Kenetek over the GA opto cell, the purest may ask for it.

Our modifications fix all of the issues and bring back the low end, smooth out the compression and bring back the character to the design.
