Within 3% matched & tested and working in circuit when shipped.
As with all vintage electronics sold as is no returns. If I do authorize a return these tubes have been documented with photos and by other undetectable means to ensure the tube returned is the SAME that was shipped to you. Your tester may not test exactly the same as mine.
