I found this while organizing the warehouse. I'm selling it because I don't use it. [Product] 5U4G Big Bottle Svetlana-S logo Vacuum Tube PX39 Svetlana Vacuum tube set of 2 [Condition] Internal inspection and professional checks have not been performed. Since the operation has not been confirmed, it is considered as junk. I do not have expert knowledge, so I may not be able to answer questions. There are no major noticeable scratches or stains, so I think it can still be used. (Please check the photos) This is junk, so please confirm thoroughly before purchasing. Also, please refrain from purchasing if you are concerned. [Accessories] Everything in the photos.
