WHAT! Tung Sol 6550 made in USA 1967 Quad, all test strong

I need to be very clear on this, I only rank these as 1/10 because I've never used them myself, not because i know or think they are broken, if you are interested and know of someone close to Charleston SC, Im happy to put them in your buddys' amp or tester. . .So, with that caveat, here is a Quad of Tung Sol 6550 made in USA ( not reissue Russian ) tubes. These tubes were last tested in 2006 and have been idle since then. I can not and will not guarantee these... as you know tubes can fail almost seemingly at random...due to me not willing to promise a guarantee, I will be forced to rate them as "scrap" in order to not get negative feedback. That being said they look to be in excellent condition. I have not owned a tube amp that uses this type in at least 11 years apparently. I also have many many NOS and excellent used tubes I have measured myself. Let me know if you want a list, I can send a PDF of them (no prices on them however). Again, an as is sale. thanks for looking. Read my feedback and buy with confidence....
