I have been running Svetlana KT88's in my power 3's with no problems. I am interested though in trying the EH6550's. I would be interested in hearing from anyone that has done a direct comparison of these tubes on power 3's.
Problems with Svetlana KT88 and Sonic Frontiers
I've heard that Sonic Frontiers has experienced problems with the Svetlana KT88 in their Power series of amplifiers. SF claims that it was due to a bad batch of tubes, and has switched to the Sovtek KT88. I would like to try the Svetlana KT88, but I am now reluctant to do so. Has anyone tried the SVKT88 in his or her Power series amplifier? What has been your experience? Thanks.
