Vintage Mullard 12AT7 kurze glatte graue Platte Tube getestet gut 1960er
31,27 €
This has really good lettering and has short smooth gray plates and appears to have a horseshoe getter with a foil strip. This has the "Mullard Flash" on startup. I tested it on my B&K 747B tube tester, and it tested at 51/54, with no shorts or grid emission, on a scale of 0-120, where 65 is minimum good and most 12AT7s test in the 50-70 range.
