Find a picture in which the GE 6650's plate construction, resembles that of the TAD version. GE: https://www.google.com/search?sxsrf=ALeKk008s9IFOesJfnELbxiV6qQDoek0rQ:1607987542896&source=univ... TAD: https://www.ebay.com/itm/Factory-Matched-SEXTET-Tube-Amp-Doctor-TAD-6550-6550A-KT88-GE-6550A-Remake-... TAD mentions the GE's triple gettering. If they have it; it must be the world's weakest, as zero side-gettering shows in any of their pics (haven't seen any up close, however, so: an assumption, on my part)

Just some general info: There are no SED, Winged =C=, Svetlana tubes, currently in production. I really liked them (bought from Upscale), but- the St Petersburg plant burned down, years ago (along with it’s equipment) and SED closed the doors. New Sensor bought the name (ONLY) and is manufacturing their version in the Sarartov, Russia plant. Some info from a reputable dealer: https://www.thetubestore.com/winged-c-sed-6550c Try contacting known to be honest tube mongers, like the above, Brent Jessee Recording, TC Tubes or Upscale Audio, for knowledgeable info, as to whether they are, "the very same exact tube." An opinion/observation regarding the new version: https://www.tubesandmore.com/comment/2577/report Compare the plate and getter construction, to the above (original Svetlana 6550) pic, here: https://www.ebay.com/itm/PLATINUM-Matched-Quad-4-Svetlana-6550C-tubes-Russia/184570896793?hash=item2... Caveat emptor (just sayin')! |
Another chi-com knock-off.
