You are bidding on a Western Electric type 421A radio/audio tube. On my TV-7D/U tester it tests strong, at 52 on one plate and 50 on the other plate, where the minimum for a good tube is a reading of 40. So it is a nice strong tube. I believe this is a new tube, as it came to me with other new WE tubes, but the box does not match its date code of 6213. It should be a great sounding tube for your project. Shipping weight is 13 ounces. No shipping to China. Please see my other auctions for more interesting radio and audio items, and tubes.
