Amperex (Heerlen made) Red Tip Medical Grade 12ax7 1952

First of all, these tubes are almost impossible to find. You can look on Ebay all day long and you will seldom if not ever find AMPEREX medical red tip 12ax7 matched pair testing strong like these. Euphoric and tonally lush they are perhaps the best of all of the 12ax7 ever made. In fact I would venture to say holy grail status could easily be given. 500 to 600 would be a fair price. I am offering these up at half that. Truly a steal and bargain. They will only go up in value folks. These are the real deal.. You want Boogle Boy amperex 12ax7 to make the cats come home. These are them. Just amazing tube and will last you a very long while. Testing measurements on in photo. thanks for looking
