Ordering Information Vintage Tubes Sales Lists Chimera Labs Home Page
NIB (New In Box), NOS (New Old Stock) or Tested Pulls (Used Tubes) sourced from vintage Audio and Military Equipment suppliers. Price per "Unit", each is the price for a single tube. Unit Price, pair is for a pair of tubes. Tubes identified as matched Pairs will also have matched sections, unless they are identified as having unmatched sections. If tubes are sold as “matched pair”, there will be no extra charge to matching. These function perfectly in circuits where each channel is amplified by both Triode Sections of the tube. Test Percentage numbers where indicated indicate how close the tube/s are to new tube readings.
Tubes with an asterisk * after the tube type are used tubes. Most of these tubes have bottom or side getters. In normal operation the silver getter flash migrates and forms deposits on the inside top of the glass envelope directly over the cathode heater tubes (the hottest part of the glass envelope). Please note that all these tubes test very strong and have a lot of life left in them as indicated by their test numbers. These used tubes are a very affordable way to realize excellent sound performance.
