Audio Research N.O.S. 6922 factory replacement tubes – quad (4)
These four tubes were purchased a number of years ago from an authorized ARC dealer. They were then placed in my “secret stash” for a rainy day. The Audio Research preamp that I had at the time is now long gone, which make these tubes available.
All tubes are Sovtek, unused as stated and come in the original white factory boxes. If you are familiar with ARC replacement tubes, they are also marked with a green circle on the bottom of each tube.
A total of 10 tubes were purchased, so if you need more than 4 tubes, please see my ads for an additional quad and pair.
