Lot of THREE Western Electric 216A triode tubes all very clean (no loose glass inside, firm metal sockets. This lot to be used WE 7A amplifier which I also offer in my other auction. The 216A is comparable with WE 101D except specd for filament voltage of 5.5-6.0V. The three 216As are fairly closely testing, ie @33-35 vs 28 specd (for WE 101D = 65%). You only buy what you see in pics. Please note that other Hickok TV-7 testers might give different test results than mine. I dont take an guarantee that these three 216A tubes will test at SAME values as I got from my Hickok TV-7 (calibrated of course). Dont bid if you disagree with my statement!
