Up for auction is this NOS/NIB strong testing quad of General Electric 12BH7 audio vacuum tubes. All four tubes were tested on my TV-7 tester where 30 is the required minimum and all four tubes had no leaks or shorts. All four tubes would make a super nice addition to anyone's collection or to use either one. Please look at the pictures above for the test results as well as the overall cosmetic condition of each tube. Thanks For Looking! All International Shi...pping Will Go Thru The Global Shipping Program, If You Do Not Like This Method Then Please, Do Not Bid!
