I’m not sure where those were made. I just purchased another quad of kt77GL from the tube store. Not sure where those are made either. Thought I would give them another try biased at 90%. I have been biasing everything at about 75%.

Well, if you didn't have to take out a loan, prolly not the UK version. :)

Those are considered some of the finest output tubes ever made. Of any manufacturer, any type (subtype), or era made. :thumbsup:
