$46 a pair
Authentic & Tested. Tubes we sell are ALL tested unless otherwise stated! All tubes are cleaned and well-taken care. Look at the photos for the highly crystal-clear glass and clean pins despite being over half a century old!
*** Please do not trust any tube seller without posting any test information on the tubes, especially vintage ones. Always check and/or request the testing or supplier information of the tubes when buying. Without test information of the tubes, you can never tell how much of the life time of the tubes is left and its condition. How to trust when tube sellers just said 'tested strong', 'works like new' such frivolous comments to certify conditions of the tubes? Worse, some tubes listed did not even come with such comments. Or it could just be a meaningless % percentile reading without context. Although the readings do not absolutely dictate and gaurantee the tubes, it is at least imperative to supply these data for a better peace of mind regardless. ***
FREE shipping with SingPost normal mail. Additional S$2.50 for tracking service.
These 6SL7s are tested by plate current instead of the usual transconductance because the input values are beyond my tester could handle. Values are obtained from characteristic plot of their graphs of the tubes data.
Typical plate current reading for the test is 0.5mA for new tubes. Typical gain values should be around 70mu for new tubes.
• Tube #1
Side A: 0.55mA / 72.7mu
Side B: 0.51mA / 71.7mu
• Tube #2
Side A: 0.72mA / 71.8mu
Side B: 0.69mA / 71.8mu

What you see is what you get. When we sell tubes we always will take various angles of it so to make sure what you select is exactly what you saw. No substitutions, no dishonest replacements.
Note: unless specifically mentioned, we do not label our out-of-production tubes as NOS (New Old Stocks), a term so commonly branded in many tubes seller. There can almost never be any guarantee these out-of-production tubes are NOS; they were mostly made in the middle of 20th century!! Who tells the tale that they are still new?? No doubt there will still be, but the changes of hands of all these stocks made this verification too difficult. To us, tubes can test excellent or test like new, but we call them all vintage tubes.
