Selling an RCA 12AU7A Cleartop tube. The date code "60-39" signifies that the tube was made the 39th week in 1960.Unlike most of the similar high-priced Cleartop tube sold, this tube has almost perfect lettering. Tests on my calibrated EICO 667 83/84, with 80 being Good. There are no shorts, leakage or gas. I have other tubes listed. I will combine shipping. Please review my feedback and purchase with confidence.
