Three of the most prized revisions of classic FET compressors in a single hardware unit

Do you love the aggressive mid-range and coloration of the 1176 blue face, the subtle character and versatility of revision D on vocals and bass and love the gentle and transparent properties of revision G on acoustic guitar and stringed instruments? Then the Stam Audio SA-76ADG is the ideal compressor for you.

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 as 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 bypass the transformers for revision G like the original.

There were 2 challenges to 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 mode, 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 and CineMag output transformer, 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.

The SA-76ADG is made with premium components

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

The SA-76ADG 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 a CineMag output transformer that precisely matches the ratio and frequency response of the original 5002 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-76ADG’s 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-76ADG, we’ll refund you

If you’ve used an original 1176 revision A, D, or G before, we’re extremely confident the Stam Audio SA-76ADG will put a big smile on your face every time you use it. However, if you’ve never touched the originals before, as gear lovers ourselves we understand that the only way to really know if this compressor is right for you, is to put it through its paces.

    This thing is fantastic. All revisions sound great, the build quality is top and it really stands out in the rack (and gets lots of compliments). The all-in buttons mode is the icing on the cake! Highly recommended.


    I have the singular version of the bluestrip rev A and it sounds amazing. For vocals it is just the trick and sounds awesome.

    This is another instant classic from Stam Audio! I grabbed a couple of these SA-76 ADG’s… and am extremely happy I did. Switching between the all the 1176 versions has been incredible. They all sound so different, and the ability to alter the vibe of your program material by simply switching through each type is VERY cool. This was such a brilliant idea from Stam, and makes these an instant classic. Each version sounds incredible… the warmth and punch of these compressors is really astounding. I’m super happy!

    The SA-76ADG is a brilliant box, having 3 revisions in one. It has a rich, elegant and harmonically dense sound that will sweeten and add vibe to anything you use it on. And the price is incredible.

    My only constructive feedback and the reason for the missing star are these few things. 1) The compression behavior of this box does not have the control that a typical 1176 has. If you’re looking for something to really clamp down and add smack to a source, this isn’t the box. It has the flavor of a 76 (3 different 76’s!), but the compression behavior is much gentler. 2) The detents of the input and output pots make setting levels challenging because their fine movement, especially on the input, has a very coarse effect. One detent might make a much more dramatic change than needed. Also, I have a pair of ADG’s and because of the slight differences in each unit’s input pots I can’t get them to match for a stereo pair because the detent’s leap-frog each other. 3) This is a non-issue but aesthetically, I’m not sure why the silkscreen for the revision radio-buttons are labeled “meter” when it should be labeled “revision” and the OFF button is labeled “on.”

    That constructive criticism aside, I love my 2 ADG’s and won’t part with them anytime soon. Great value for the price. Thanks, Stam.

    Simple and extremely well-built compressor. I have no doubt that it will last for a long time. The fact that you are able to change between “A” “D” and “G” with just a press of a button is amazing innovation which helps my workflow immensely. Own the unit for almost 6 months now and haven’t had a regret one single time for buying it. As far as sound is concerned, the knobs are made in a way which enables me to both smoothly and rapidly dial in order to find the right level of affecting the source. Buttons are well made (no popping out or something similar). I was only surprised that unit was off when on is pressed, but, regardless, I am giving this unit 5+ stars for sound alteration and quality. Affordable and amazing outboard!!! Well done STAM.

  6. Eric

    Great pro sound. Easy to use even if turning off and on and bypassing the compression is a little confusing. Still an amazing piece and compression wise what else do you need. Loving tracking with it 🙂

    This is my second 1176 purchase from Stam Audio. The first being the original blue stripe (Rev A), FET model, which has happily served me well for many years especially on bass, and sometimes vocals . I couldn’t pass up on having 3 1176 revisions in one unit. I find having the extra Rev D and G option very handy. Sometimes my Stam Blue stripe REV A clamps down too quick on certain vocal consonants, so I’m now using the ADG (D/G mode), more on vocals if I need a slightly slower action, song/ tempo dependent. 95% Metal film resistors throughout, so I imagine it will sound cleaner than an original, and definitely remain more stable for 20+ years. I know Josh had to iron out some bugs with the original design of the earlier units, like mine, and it created a few headaches/ holdups.Thankfully he has a calibration procedure on the website, for people like me who have the technical ability to fix any underlying issues. After a bit of tweaking, I’m really happy with my unit now. I can see, these Stam designs improving with age, and those who purchase in the future, will reap the rewards of all the trials and tribulations due to innovation and hard work.

    STAM -76ADG is really good. This is my first piece of STAM gear and it was worth the wait. Great harmonic distortion when you push it, subtle when you need it to be…it’s gonna get a lot of work in my studio. Build quality is excellent.
