One Pair NOS Western Electric 300-B original issue test new

One pair NOS Western Electric 300-B new issue

One pair NOS KR Audio KR-300BXL

No you are not seeing things, these are original NOS Western Electric 300-B’s. I bought these back in 2004 from as you can see on the boxes Upscale Audio. I have kept these in this Pelican case which comes with these tubes. I have only taken them out to test them when I bought them and now that I am selling them. Upscale had a few of these and I was lucky enough to pick up a pair. I have never used these in any amp as I don’t own a 300-B amp and saw them as too valuable to waste. You can see the test results (from Upscale Audio) on the side of the boxes. I have tested them in my tester and they all test new. When I bought them I intended to use them in some 300-B amp I had my eye on. I never bought the amp, so I thought I should send them down the road to somebody who does have a 300-B amp. As you can see it comes with a pair of the new issue Western Electric 300-B’s (also New) as well as a new pair of the KR Audio KR-300B’s. USA only unless buyer wants to pay shipping. Prefer them to be picked up, but will insure them for the purchase price, if shipping is necessary.
