IMPORTANT: Amplifer damage can occur if the wrong type of tube is used. Before ordering please verify the type of tube used in your amplifier.<\/li><li>6N3P-E is a VINTAGE Russian dual-triode 9-pin vacuum tube that was manufactured by the original Reflektor plant in Russia. This long-life tube (denoted by the \"E\" suffix) has 3 mica-spacers and is considered an exceptional audio tube.<\/li><li>Tested and Matched using Amplitrex AT1000 tube testers to evaluate the electrical parameters of the tubes.<\/li><li>Data labels for Gm (mutual condutance), Vg (grid voltage) and tube gain (\u00b5) are attached to the tube boxes (tested using auto-bias mode). The tubes chosen for these special matched-pairs have very good balance between tube sections and close electrical parameter matching between the tubes. Tubes are matched within 6% for Gm, Vg and tube gain. Individual matched pairs will have identical manufacture date-codes.<\/li><li>2-year warranty. All Platinum Grade vacuum tubes are backed by our no-nonsense two-year warranty. We also guarantee that the tubes selected for our matched pairs test at NOS levels. For protection during shipment, we use tube boxes designed by Riverstone Audio (our \u201cTube Cradle\u201d boxes). Vacuum tubes sold by Riverstone Audio will have the \"Riverstone Audio\" name, logo and QC label on the boxes.<\/li><\/ul>        <\/div>\n    <\/div>\n\n    <div class=\"aawp-product__footer\">\n\n

Of these, Russian 6N3P are made with high quality and works very well in audio applications. For more information on Russian and Chinese 6N3P, see 6N3P Equivalent Tubes <\/p>\n<h4>Q: What is the difference between 2C51 \/ 5670 and 6N3 tubes? <\/h4>\n<p>A: Stay well, stay safe. 2C51 \/ 5670 tube is a medium gain dual triode tube. 5670 tubes saw wide use radios, as well as high fidelity audio gears. 6N3 is the Russian\/Chinese version of the same tube. We stock the different versions for those who are looking to upgrade or tube roll. <\/p>\n<h4>Q: Where were the 2C51 \/ 5670 \/ 6N3P made? <\/h4>\n<p>A: 6N3P were produced at several Soviet tube factories &#8211; Reflektor JSC in Saratov Russia, Voskhod JSC in Kaluga, Russia, and mysterious Oktjbr&#8217; factory in Vinnitsa, Ukraine. All of the 2C51 \/ 5670 and descendants are drop-in compatible despite having very different names. <\/p>\n<h4>Q: Why is it called 6N3P in China? <\/h4>\n<p>A: 6N3P designation came from now-defunct USSR. It was 6H3\u041f in Cyrillic. When us Westerners saw the Cyrillic letters on the tubes, they looked like 6N3P &#8211; so we called it 6N3P. Chinese military licensed (copied?) 6N3P from the Soviets, but Chinese also couldn&#8217;t quite deal with Cyrillic. So the Chinese tube manufacturers designated the tube 6N3P. <\/p>\n<h4>Related Post:<\/h4>\n<ul>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/6n3-preamp\"><span>6N3 Preamp<\/span><\/a><\/li>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/bob-replacement-inner-tube\"><span>Bob Replacement Inner Tube<\/span><\/a><\/li>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/test-tube-vase-replacement\"><span>Test Tube Vase Replacement<\/span><\/a><\/li>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/raychem-heat-shrinkable-tube\"><span>raychem heat shrinkable tube<\/span><\/a><\/li>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/flexible-stainless-steel-tube\"><span>flexible stainless steel tube<\/span><\/a><\/li>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/empty-mascara-tube-sallys\"><span>Empty Mascara Tube Sally&#8217;S<\/span><\/a><\/li>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/red-tube-mascara\"><span>Red Tube Mascara<\/span><\/a><\/li>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/tube-sinker\"><span>Tube Sinker<\/span><\/a><\/li>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/girl-boy-tube\"><span>Girl Boy Tube<\/span><\/a><\/li>\n<li><a href=\"https:\/\/romanceuniversity.org\/best\/tube-light-with-frame\"><span>Tube Light With Frame<\/span><\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The Best 6N3 Tube Replacement of 2025 &#8211; Reviewed and Top Rated After hours researching and comparing all models on the market, we find out the Best 6N3 Tube Replacement of 2025.
