Purple Audio MC77 is a standard 19″ two space rackmountable limiter. The MC77 recreates the audio circuitry of the revision E 1176, using modern components matched to the original.

One significant component is the input attenuator. The input attenuator that was custom made for the original revisions A-F 1176 and for the Purple MC76 by Clarostat was discontinued in 2002. It was a J series T-pad attenuator with two 600 OHM “build out” resistors to keep a constant 600 OHM load on the source and primary of the input transformer. Clarostat changed carbon manufacturers and the new carbon manufacturer was unable to make the part. Purple temporarily stopped making the MC76 to find a solution. We tried several three deck Clarostat 70 series pots in different configurations to achieve the same loading and to match the taper. We found a solution that matched the original. Based on that feedback, from hundreds of satisfied MC76 users we incorporated useful new features into the new MC77.

Highland Dynamics BG2

Write less automation. Find more enjoyment. The Highland Dynamics BG2 is an all-tube, fully transformer-balanced “very-mu” compressor with automatic leveling capability, but there’s much more to it than mere leveling.

The BG2 is a marriage of classic tube compressor topologies. Its front end is in the style of a British-modified modified Altec 436 while its twin 6V6 output amp is reminiscent of the venerable RCA BA6A and Gates output stages. The result is a compressor with heavy tube character that sounds more airy and spacious than most.
