It is designed for power amplification. Its high dissipation, strict manufacturing tolerances, and meticulous processing give it increased reliability and superior sound performance. The Svetlana KT88 is manufactured at the SVETLANA factory in Saint Petersburg, Russia, and is designed to be a direct replacement for any KT88, KT90, KT99, or 6550. The new KT88 offers significantly improved sound performance: increased peak cathode emission thanks to new cathode materials; stable operation thanks to extended processing and aging; gold-plated grid; new three-plate anode; monoblock beam forming electrode; precise grid\/screen alignment; improved vacuum processing; comprehensive static and audio amplifier testing before and after aging.\u0026quot;,\u0026quot;https:\/\/encrypted-tbn0.gstatic.com\/images?q\\u003dtbn:ANd9GcTdPNikop4c2FnQlDkAz34R_72MgNzbuCqgNsp020grNjg9FxIN3O8W2HA03Wg95CoxwDcT1hfU6BJa2Wg\u0026quot;,\u0026quot;Audiophonics\u0026quot;,\u0026quot;https:\/\/encrypted-tbn2.gstatic.com\/faviconV2?url\\u003dhttps:\/\/www.audiophonics.fr\\u0026client\\u003dAIM\\u0026size\\u003d128\\u0026type\\u003dFAVICON\\u0026fallback_opts\\u003dTYPE,SIZE,URL\u0026quot;,[[1792967711619477,4279261,3223981948],null,null,null,null,[[2,0,0,10]]],null,\u0026quot;37f35364-a6d2-4e5a-b534-6d0c0468a41c\u0026quot;]]--\u003e\u003c\/span\u003e is a \u003cmark class=\"b6AQX\" data-wiz-attrbind=\"class=FUl3fc_w\/cFwyDc\" data-sfc-root=\"c\" data-ved=\"2ahUKEwiV862cndaXAxXdS0EAHXwPKsAQuJAPegoIAggACAAICRAE\" data-complete=\"true\"\u003eglass-enclosed beam power tetrode vacuum tube designed for high-end audio frequency power amplification\u003c!--TgQPHd|||[[[null,null,null,null,null,null,null,null,null,null,null,null,[247864,null,0]]]]--\u003e\u003c\/mark\u003e and as a direct replacement for KT88, KT90, KT99, and 6550 tubes.\u003cspan\u003e [\u003ca href=\"https:\/\/www.audiophonics.fr\/en\/svetlana-tubes\/svetlana-kt88-p-21080.html\"\u003e1\u003c\/a\u003e, \u003ca href=\"https:\/\/frank.pocnet.net\/sheets\/164\/k\/KT88spec.pdf\"\u003e2\u003c\/a\u003e]\u003c\/span\u003e\u003c!--TgQPHd|||[]--\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"yhAwj\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-complete=\"true\" data-sfc-inited=\"2\"\u003e\u003c!--TgQPHd|||[]--\u003e\u003c\/div\u003e\n\u003cdiv class=\"ZLzG0d ncoeY E8xBUb\" role=\"heading\" aria-level=\"3\" data-animation-nesting=\"\" data-sfc-cp=\"\" data-wiz-attrbind=\"aria-level=FUl3fc_15\/fLk2Md\" data-sfc-root=\"c\" data-complete=\"true\"\u003eKey Features \u0026amp; Specifications\u003c!--TgQPHd|||[[2,[null,null,null,null,null,null,null,null,null,null,null,null,[351768,null,0]],[],null,1]]--\u003e\n\u003c\/div\u003e\n\u003cdiv data-bfc=\"\" class=\"\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-ved=\"2ahUKEwiV862cndaXAxXdS0EAHXwPKsAQi4wTegoIAggACAAIExAB\" data-hveid=\"CAIIAAgACBMQAQ\" data-complete=\"true\"\u003e\n\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-complete=\"true\"\u003e\u003cstrong class=\"rQesXe MPyX\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-complete=\"true\"\u003eDesign \u0026amp; Construction:\u003c!--TgQPHd|||[]--\u003e\u003c\/strong\u003e Features a gold-plated grid, a tri-plate anode, a single-piece beam-forming electrode, and a third mica layer for reduced noise and mechanical vibration.\u003c!--TgQPHd|||[]--\u003e\u003c\/span\u003e\u003cspan\u003e [\u003ca href=\"https:\/\/www.youtube.com\/watch?v=slaOeBpnaIA\u0026amp;t=15\"\u003e1\u003c\/a\u003e, \u003ca href=\"https:\/\/www.audiophonics.fr\/en\/svetlana-tubes\/svetlana-kt88-p-21080.html\"\u003e2\u003c\/a\u003e]\u003c\/span\u003e\u003c!--TgQPHd|||[]--\u003e\u003c!--TgQPHd|||[]--\u003e\n\u003c\/div\u003e\n\u003cdiv data-bfc=\"\" class=\"\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-ved=\"2ahUKEwiV862cndaXAxXdS0EAHXwPKsAQi4wTegoIAggACAAIExAI\" data-hveid=\"CAIIAAgACBMQCA\" data-complete=\"true\"\u003e\n\u003cspan class=\"iNqyIf\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-complete=\"true\"\u003e\u003cstrong class=\"rQesXe MPyX\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-complete=\"true\"\u003ePower \u0026amp; Ratings:\u003c!--TgQPHd|||[]--\u003e\u003c\/strong\u003e Can handle up to 800 volts on the plate and up to 42 watts of plate dissipation.
