This DOA is an eight transistor amplifier modeled after the legendary Melcor 1731. For those who do not know it, many of the engineers responsible for the Melcor 1731 left Modular Audio Products around 1968 to join forces with Saul Walker when he started API. The starting point for the famous API 2520 was indeed the Melcor 1731. Back to the beginning I guess one could say!<\/p>\n<p>Overall, it&#8217;s sonically very similar to the sound of a 2520. The gar1731 has a slightly smoother bottom and top, while simultaneously retaining the ever familiar aggressive, forward midrange we love about the 2520.<\/p>\n<p>Modeled after the Melcor 1731 (the direct predecessor that Saul Walker used as the baseline when designing the original 2520), it offers thick low-mid-range weight. Many users like combining a 1731 in the first stage and a 2520\/0252 in the second stage for a balanced response.<\/p>\n<p>Some of the applications the gar1731 DOA can be used for:<br \/>\n\u2022\tMicrophone Preamplifiers<br \/>\n\u2022\tLine or Booster Amplifiers<br \/>\n\u2022\tLossless Combining Amplifiers<br \/>\n\u2022\tBalanced Transformerless Amplifiers<br \/>\n\u2022\tEqualizers and Compressors<\/p>\n<p>Additional features and specs:<br \/>\n\u2022\tIndustry standard 2520 footprint for plug-in or PC mount connections<br \/>\n\u2022\tLow noise, high power output<br \/>\n\u2022\tLow distortion<br \/>\n\u2022\tMinimum load impedance is 75 ohms for full output voltage<br \/>\nPower supply voltage is bi-polar +\/- 12 VDC to +\/- 20 VDC<\/p>\n<p>gar1731  Melcor 1731  ver.4.1 2015<\/p>\n<p>Fully built to perfection in Canada with a 1 year warranty.<br \/>\nAssembled with Kester solder.<br \/>\nThese can be also build to order.<\/p>\n","protected":false},"featured_media":1222,"template":"","meta":{"_acf_changed":false},"product_cat":[53],"product_tag":[],"class_list":["post-1254","product","type-product","status-publish","has-post-thumbnail","product_cat-op-amps","product_shipping_class-opamps","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/bywaudio.com\/index.php\/wp-json\/wp\/v2\/product\/1254","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/bywaudio.com\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/bywaudio.com\/index.php\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/bywaudio.com\/index.php\/wp-json\/wp\/v2\/media\/1222"}],"wp:attachment":[{"href":"https:\/\/bywaudio.com\/index.php\/wp-json\/wp\/v2\/media?parent=1254"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/bywaudio.com\/index.php\/wp-json\/wp\/v2\/product_cat?post=1254"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/bywaudio.com\/index.php\/wp-json\/wp\/v2\/product_tag?post=1254"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
