I found these while organizing the warehouse. I'm selling them because I don't use them. [Product] RCA JAN 6C5 VT-65 Vacuum tubes, set of 4 (3 marked K6E, 1 marked K5E) *Please refer to the photos to determine the detailed model number as I lack specialized knowledge. [Condition] I have not performed internal checks or specialized inspections. Since the operation has not been confirmed, they are considered junk. I do not have specialized knowledge, so I may not be able to answer questions. There are no major noticeable scratches or stains, so I think they can still be used. (Please check the photos) These are junk items, so please confirm before purchasing. Also, please refrain from purchasing if you are concerned. [Accessories] Everything in the photos. [Notes] ⚠️Please refrain from purchasing if you are nervous, as these are stored at home. ⚠️We make every effort to inspect before shipping, but please understand that there may be small stains or scratches. ⚠️Returns are not accepted for reasons such as "different from the image." Please refrain from purchasing if you are looking for perfection. Shipping will be via either Yu-Yu Mercari or Raku-Raku Mercari. Instant purchase OK #RCA #JAN #6C5 #VT-65 #VacuumTube
