Important Notes Regarding vacuum tubes: I am listing these, but I ask that those who can judge from the photos please bid. m(_ _)m This price is for everything in the set. Only the items shown in the photos are included. They have been opened. It is unknown whether they are used or unused. Due to my lack of knowledge, I have not confirmed that they are fully functional. Currently, they are listed as junk items. (I don't know if they work) These are items that were included with a product I purchased. Because they are junk items, the overall condition is listed as poor. Currently, they are treated as junk items. Please refrain from purchasing if you are sensitive to this or if you are seeking perfection. m(_ _)m They will be simply packaged for shipping! Please understand the above points and the profile section before purchasing. Instant purchase OK. Comments are also OK. ^_^ Keywords: Vacuum tube Vacuum tube amplifier Vacuum tube radio Vacuum tube junk Used vacuum tube Preamplifier Booster Overdrive preamp booster overdrive 12AU7 sylvania 6J1 vacuum tube 42KN6 Mil-spec selected grade EL84EH USA vacuum tube GE tube tube vacuum tube NATIONAL NATIONAL vacuum tube Nixie tube
