Original Description:
Up for sale here is this nice lightly used matched pair of vintage Sylvania 12AU7 tubes.  These have long ribbed black plates and top angled D getters, and have matching 1953 date codes.  Most of the lettering is gone, but these originally had 318 date codes, for the 19th week of 1953.  These are some of the best 12AU7 options out there, and this pair is very strong, testing close to NOS levels.
I tested these on my calibrated B&K 747B tube tester, and they tested... at 81/81 and 83/81, with no shorts or grid emissions, on a scale of 0-120, where 65 is minimum good.  These are nice strong tubes and are guaranteed to work for you.  Please see my pictures for details.

US shipping and handling is $4, and international is $14.  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!
