The Winged "C" is musical and lush, with plenty of liquid. So far all of the offerings I tried from New Sensor seem to lean toward a dry, and almost sterile sound. The last new stock Tungsol still seams to have their (New Sensor) house sound, maybe a little more detail than the SED. Their sound still reminds me of their Sovtek line. The SED (Winged "C") seems to have more problems again. This is my experience.
Thoughts on current EL-34 tubes
I have just put my Jolida JD-1000P back into my system, and when I initially fired it up one of the tubes was obviously bad giving a good light show. I found this kind of strange as the amp has been sitting idle with no power to it for about six months now and the tubes Winged C Svetlanas were working fine when I took it out of the system. I replaced the winged C with another Svetlana for now and ordered up 8 matched Tungsol re-issues as I have heard that these tubes are some of the better of the re-issue tubes out now, what are everyones thoughts on current re-issue EL-34 tube available now.
