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.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eTrue Bypass via sealed relay w\/front panel switch\u003c\/li\u003e \u003cli\u003eImproved stereo linking w\/front panel switch\u003c\/li\u003e \u003cli\u003eSidechain insert loop or key input w\/front panel switch\u003c\/li\u003e \u003cli\u003eBuffered VU meter can monitor input or output level at +4dBu\u003c\/li\u003e \u003cli\u003eLED meter lights that don’t burn out\u003c\/li\u003e \u003cli\u003eHeavy gauge black cold rolled steel enclosure\u003c\/li\u003e \u003cli\u003eDiscrete Transistor Audio Path Electronics\u003c\/li\u003e \u003cli\u003eSingle Element Class A Output Amplifier\u003c\/li\u003e \u003cli\u003eTransformer Balanced XLR Inputs and Outputs\u003c\/li\u003e \u003cli\u003eZener Shunt Regulated Audio Power Supply\u003c\/li\u003e \u003cli\u003eRuggedized Design – PCB stiffener, chassis mounts\u003c\/li\u003e \u003cli\u003ePurple Anodized Aluminum Front Panel\u003c\/li\u003e \u003cli\u003e3 Year Warranty\u003c\/li\u003e \u003c\/ul\u003e","brand":"Purple Audio","offers":[{"title":"Default Title","offer_id":49567726356,"sku":"189203","price":9205.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2241\/9163\/products\/53d15720a4ac6a1805de2d4ac3bf8d8d.jpg?v=1504264016","url":"https:\/\/collection-import-export.myshopify.com\/products\/purple-audio-mc77-discrete-class-a-limiting-amplifier-e-1176-type-compressor","provider":"collection-import-export","version":"1.0","type":"link"}
