These are the original Sovtek 6L6GB tube from before New Sensor bought the name. NOT 6L6GC! Compatible with all 6L6 variants except 6L6GC, which require a higher plate voltage rating. They are unused old stock made for OEM amp makers so there is no label or logo. They have the flying saucer getter only seen in real Sovtek and Svetlana. They sound awesome and are very sturdy in construction.
Tested on the RoeTest professional computer testing system.
Matched sets are matched by plate current and transconductance using the new Maxi Matcher 2
