Up for sale here is this vintage Sylvania 12AU7 tube. This has long ribbed black plates, a top bent D getter, and a nice patch of silvering. It is dated 335, for the 35th week of 1953. This is an extremely early 12AU7.
I tested this on my calibrated B&K 747B tube tester, and it tested at 34/39, with no shorts or grid emissions, on a scale of 0-120, where 65 is minimum good and most used 12AU7s test in the 40-70 range. This is a little on the low side, but... is still a good tube and is guaranteed to work for you. Please see my pictures for details.
US shipping and handling is $4, and international is $16. All my small parts are set up for combined shipping, so just use the "add to cart" feature and then check out all at once, and it will combine shipping. I accept Paypal. If you have any questions, please ask.
I have more great tubes and other vintage electronics listed--feel free to take a look!
