Three famous revisions of classic FET compressors in a single hardware unit

Following our highly successful SA-76ADG release we decided to go one step further and incorporate the all-time favorite F revision into our 3 in 1 compressor topology by respecting the original schematic and adding a third Altran output transformer to the signal. We have also added the Super Slow Attack switch and 2:1 ratio from the AD revision (Anniversary Edition) making this a 4 in 1 compressor.

As we were already planning to do a 1176 model of each famous revision, it occurred to us, why make just one if we could deliver all 3 versions to our clients, at the same price a single unit? Mechanically and component-wise the cost was marginally higher and we could use both the 0-12 and 50002 transformers for the A and D sections as used on the original units and the 0-12 and B11148 transformers for revision F like the original.

There were 2 challenges to be overcome. First, each revision had to sound 100% identical to the original by respecting the original signal path and schematic. Secondly, it had to look like an original 1176. We removed the +4 and +10 metering options and left the VU meter in standard Gain Reduction mod, in order to utilize the original switches to select between which revision you want. With the aid of several relays we have insured that you can switch from one version to another, seamlessly respecting the original sound.

Each unit comes with a Sowter input transformer O-12 replica, two Altran output transformers, Philip capacitors, Ohmite carbon comp resistors, tantalum and the correct output transistors, 20N3055 on the D revision and 2N5055 on the A revision.

Commercially, it would have made more sense for us to release all 3 revisions separately and it would have meant selling more units…but for us at Stam Audio, it is important for us that you get the most out of your money, as well as optimize rack space.

You can now have the 1176 revision A, D and F at only $899.00 USD with the highest quality premium components available in the world, and the finest transformers found on the market at a fraction of the price of one unit, let alone three.

The SA-76ADF is made with premium components

We have gone to great length to faithfully reproduce the compression characteristics and tonality of the original.

The SA-76ADF features a Sowter 1260 input transformer which is an identical replica of the original UTC O-12 (Ratio 1:1.58 200/500 Ohms) and two Altran output transformers that precisely matches the ratio and frequency response of the original 5002 and B11148 output transformer designed by Bill Putnam. We have made no compromise in parts such as Vishay capacitors, NOS carbon resistors and matched selected transistors to ensure you will get the best sounding unit without cutting any corners. All of the SA-76ADFs are calibrated in our workshop in Chile where they get their transformers soldered, a full health check, and a burn for 24 hours.

100% satisfaction guarantee – if you don’t love your SA-76ADF, we’ll refund you

If you’ve used an original 1176 revision A, D, or F before, we’re extremely confident the Stam Audio SA-76ADF will put a big smile on your face every time you use it. However, if you’ve never touched the original before, as gear lovers ourselves we understand that the only way to really know if this FET compressor is right for you, is to put it through its paces. That’s why the SA-76ADF comes with a 30 day money back guarantee. This allows you to get it into your rack and see how it impacts your recordings. If you love it (and we think you will!), great…keep the unit and create amazing music with it. If not, no problems. Just send it back to us and we’ll fully refund your purchase. And don’t worry, Whichever way you decide to go we will remain friends.
