CLASSIC COMPRESSION. BREAKTHROUGH PRICE.
The Stam Audio SA-76ADF is an exact replica of the 3 most revered revisions of the UREI 1176 FET compressor. Revision A, D and F.
Following our highly successful SA76-ADG 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 Cinemag B11148 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 Cinemag 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.
We have gone to great length to faithfully reproduce the compression characteristics and tonality of the original.
The SA76ADF 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 Cinemag 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-76’s are calibrated in our workshop in Chile where they get their transformers soldered, a full health check and a burn for 24 hours.
