4 pc. GE Lear 12AY7 Vacuum Tube Amplitrex Tested - All 100% Gm+ - Nice Quad

Description: Up for sale, a quad of vintage GE 12AY7 (originally yellow labeled for Lear) tubes. I have a big bag of these somewhere but stumbled across these 4 today that got isolated from the bunch. They test really nicely and so close to each other I thought I'd just list them as a quad. Not sure anyone needs a set like this but here it is nevertheless. These are all the same construction, 2 mica and square getter. The exact test results are shown in the pics. These show typical wear from age and do NOT have original boxes. I'll wrap in bubble wrap for a safe journey. US bidders/buyers only please. These will ship tracked and insured. General notes regarding testing: tubes are tested using fixed bias which produces the most conservative results. The tester is fed 116.4v pure sine wave battery power which allows for extremely consistent test results. My wall voltage measures all over the map and consistency suffers a bit so I've unplugged. My test rig is pictured for reference.
