76F "Rev F" FET Compressor/Limiter
76F "Rev F" FET Compressor/Limiter
A zero-compromise, component-for-component recreation of the legendary (and highly underrated!) Urei 1176 Rev F. Like our 76A and 76D units, the 76F incorporates the best-in-class Cinemag CM-O12 input transformer, a crucial part of the 1176 sound, but pairs it with an equally precise custom replica of the original Rev F’s Bournes B11148 transformer on the output. Combined with period-correct carbon film resistors in the audio path and other premium components throughout, this is simply the most authentic “Rev F” 1176 money can buy!

An Authentic Recreation Of The Most Underrated 1176 Revision
The 1176 Revision F is, in our opinion, the real sleeper of the 1176 lineup. Everybody knows the blue stripe “Rev A” and black panel “Rev D,” but this later revision - built with slightly more modern components (carbon film instead of carbon composition resistors, for example) and the brighter, more aggressive-sounding B11148 output transformer - often gets overlooked.
It’s long been one of our favorites here, so we set out to nail this revision even before taking on the much more popular Rev D.
Quality In, Quality Out
If you’re familiar with our 76A or 76D, you know we are what you might call “obsessive” when it comes to the component selection for a truly authentic 1176 build. Yes, you can use modern parts, follow the available schematics, and end up with something that definitely resembles a vintage compressor. But if you want to nail the originals, you have to use original-style components.
It Starts With Iron
Like our 76A and 76D, the 76F prominently features a Cinemag CM-O12 input transformer - by far the most authentic-sounding replica of the famous UTC O-12 “Ouncer” used in the original Urei units. For some reason, no other manufacturer out there has picked up on this. We evaluated every modern transformer option available while designing our 76 circuits, and this one smokes any off-the-shelf transformer out there. Cinemag completely nailed it!
Because the B11148 plays such a crucial role in the box tone of the Rev F, we went to our transformer guru and spent months working on a custom-wound replica. The result captures all the bright, modern polish of the original while retaining some vintage 1970s character. It’s the perfect complement to the aggressive midrange bite of the 76A and the smooth, rich harmonic tone of the 76D.
Vintage 1176 Parts = Vintage 1176 Sound
Where most 1176 recreations fall short is in the FETs used in the compression section. It’s a “FET” compressor, so getting this part right is essential. Modern JFETs won’t cut it. We’ve been stockpiling NOS 1970s FETs for years, and won’t use anything else in our 1176 builds. Having access to the NOS component market is a huge advantage of building here in the USA, and it’s probably why no other manufacturer has gone this route.
A More Modern 1176 For Vocals, Bass, And Acoustic Guitar
The slightly more modern components and design of the Rev F give it a shine and polish not usually associated with this style of compressor. We’ve heard it aptly described as sounding like “liquid gold.” Combined with the slightly slower attack and better low end handling compared to the earlier revisions, the 76F is right at home on modern productions - perfectly suited to pop or rock vocals, bass guitars, and even kick drums. It especially shines on acoustic guitar.
Like the other AudioScape 76 compressors, the 76F stands out from the field in its ability to hold up even when cranked to the maximum. Inferior 1176 builds, like many plugins, show their weaknesses at high compression settings, falling apart and failing to keep up with aggressive transients. The 76F will put up with anything you can throw at it, with excellent low end retention even under heavy compression - even outperforming the 76D in this regard.
Premium, Vintage-Accurate Components Throughout
True to AudioScape form, we use only the highest-grade parts that match the original sonics in this unit. The audio path features carbon film resistors like the original units, with high-quality precision metal film resistors in the sidechain, where accuracy is needed.
