To our ears, it is indistinguishable from the CMC5U. This project&#8217;s been on the shelf for over 2 years, so we are happy it&#8217;s complete.<a href=\"https:\/\/txsound.com\/blog\/wp-content\/uploads\/2014\/11\/interior.jpg\"><img loading=\"lazy\" class=\"alignright size-large wp-image-571\" src=\"https:\/\/txsound.com\/blog\/wp-content\/uploads\/2014\/11\/interior-1024x711.jpg\" alt=\"interior\" width=\"625\" height=\"433\" srcset=\"https:\/\/txsound.com\/blog\/wp-content\/uploads\/2014\/11\/interior-1024x711.jpg 1024w, https:\/\/txsound.com\/blog\/wp-content\/uploads\/2014\/11\/interior-300x208.jpg 300w, https:\/\/txsound.com\/blog\/wp-content\/uploads\/2014\/11\/interior-624x433.jpg 624w, https:\/\/txsound.com\/blog\/wp-content\/uploads\/2014\/11\/interior.jpg 1685w\" sizes=\"(max-width: 625px) 100vw, 625px\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>Now for a few shoot days to\u00a0\u00a0beat it up in the field\u00a0to make sure the mods hold.\u00a0It takes about 9 component additions\/changes, a some trace cuts, and a couple of trace bridges. Matching some component pairs, and some delicate rewiring , so you don&#8217;t melt anything\u00a0or break component leads. Removal and replacement of silicon stabilizer, as some of the components are covered in it. Very good soldering and wiring skills required, and the ability not to over-work component leads or lift traces. \u00a0Anyone interested, see <a href=\"http:\/\/www.cmc4upgrade.com\">www.cmc4upgrade.com<\/a><\/p>\n<p>by Pete Verrando<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A CMC4U preamp from Schoeps won&#8217;t see much use these days, as &#8220;T&#8221; powering becomes less available, less popular, and technically antiquated. \u00a0What a waste! \u00a0Not wanting to destroy a perfectly functioning (and expensive) condenser mic preamplifier, this was approached with some careful deconstruction\u00a0and if things went awry, \u00a0a planned exit strategy to salvage the [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":574,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[7],"tags":[],"_links":{"self":[{"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/posts\/563"}],"collection":[{"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/comments?post=563"}],"version-history":[{"count":7,"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/posts\/563\/revisions"}],"predecessor-version":[{"id":573,"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/posts\/563\/revisions\/573"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/media\/574"}],"wp:attachment":[{"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/media?parent=563"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/categories?post=563"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/txsound.com\/blog\/wp-json\/wp\/v2\/tags?post=563"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
