Description
Total of 5 tubes. All test good for filament. I have not tested for strength. Two Cunningham 301A, 2 RCA RADIOTRON UX201A and a SilverTone 201A-G -130. There are some old markings on the bottom underside base from past test, I don’t know if those are valid today or not. One of the Cunningham is a gold hue color. Free shipping in USA
