The KT88 first came out in 1956 so according to the date code on the Bakelite pair they are from November ML 4 and December 1956 MM 4. So these are first production (1st generation). Anybody know what month they began production and coding? The second pair are 2nd generation KT88s same glass as generation 1 but with metal bases Date codes put them at March 57 NC 4 and December 57 NL 4 These were purchased back in the 1960's by an engineer (now retired 78 years young) They were put into a storage box and forgot about. About a month ago I was introduced to him and I have these wonderful tubes now. They appear to be NOS NIB. The boxes are crisp and clean, the inner envelopes are present and the Logo's on the tubes are primo. Testing as new on my tester. Trying to research these first generation KT88's is almost futile. There is no information out there anywhere. What gets me more is that when you go to google images not one picture of these original style glass come up. Are these tubes really that rare? Nothing is coming up on ebay present or past. Maybe they should be in a museum and what would be a real market value. Hard to put a price on something that you never see for sale let alone ever see! Thoughts comments anyone? |
