I owned the Power 3s about 5 months ago and was also told of to avoid Svetlanas. I went ahead and used the Sovteks and never went back, I found them to be very nice sounding in the MIDS. From what I understand, If SF runs the tubes at a very high bias, and the Svets were blowing at whatever the biasing point is. I did try the Ei90s, the Newest Chinese kt88s (the name escapes me now) and the Sovteks just did everything about right
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.
