The Sylvania Tektronix 212AT7E tubes arrived today and they look very nice. Unfortunately the Sylvania print is almost worn off of them but they look very tight, clean and unused. They also tested higher than most 12AT7's, coming in at 4900/4600 and 4500/4300. I have not had the chance to give a listen yet. Does anybody know why they are designated "E" under the 12AT7 acid etch.
