ECC82 12AU7 Valvo, tests NOS and balanced, vintage Heerlen production
Out of stock
Valvo ECC82/12AU7 made by Philips Heerlen (Amperex/Bugle Boy factory). Code on tube is delta2D2 (=Heerlen, 1962, April, week 2). This tube may have seen minor use. It tests perfectly and still better than new with 18mA/18mA with 17mA being the 100% value of a new tube. I do not have the original box for this one but will pack it very carefully.
