Since TungSol 6550's are about $600-$900 quad, and GEC's $1200-$2000 quad, Svetlana's KT88's are about the best I have heard, for reliability, and sonics. The ones with the wing C logo, are the ones made by the factory in St. Peterburg. The others labelled Svetlana are made by Reflektor, which makes the tubes sold under the Sovtek banner.If you have the bucks, the vintage tubes, do sound better, and tend to last 3-5 times as long.
Good 6550/KT88 tubes
Hey folks,
Can someone tell me what the sonic differences are between the Svetlana KT88 and 6550c tubes are? Also I heard that the Tesla KT88 tube is one of the best production KT88's out there? Any comment? I am looking to tube my Rogue Magnum 120's and could use the help. Any tube suggestions would be appreciated.
Thanks guys
