NOS New Old Stock, usually from old inventory from out of business retailers. Boxes can show significant shelf wear.
For Tube Folks...
Hi All,
I am rather new to tube gear and recently purchased a 'NOS' GE 6550 Power Tube.
A. It was advertised as: "New old stock in original or OEM box. A nice USA tube that will outperform any current production 6550 made. An excellent lot, matched to within 5 percent and then aged in a hi-fi shop demo unit. Very low hours, burn-in time only, and the performance has been verified by us..."
B. The seller also sells used GE6550 tubes that are advertised as: "Light use, tested good with good match, and white box..."
The large black spot on the glass where it GE is etched makes wonder how many hours of usage this tube has seen...
My question - Within reasonable certainty, is this tube is NOS or is it USED?
Thanks in advance for any clarity.

Even new tubes are tested by resellers before they're sold. A while back, I bought four Telefunken military grade tubes for a radio multiplex. I got them on eBay and the seller was, I believe, an old Ham Radio Operator and these were from his own collection. He had an Amplitrex tester and was very transparent about the whole process. I just had to make the decision on whether or not to trust him and now, I'm really glad I did. But this was long ago, way before the insane prices that we now see for NOS Telefunkens. Currently I'm in the market for a Linlai E 6sn7. I've decided that there are some new tube manufacturers that offer a better value than those highly coveted Western Electric, etc... Plus when you by a new tube, it comes with a warranty. |
@ghdprentice once I went to your pictures - it appears you are quite the photographer. Thoroughly enjoyed some of your city shots after the tubes. You know how to make a camera sing ! |
