I have a matched pair of RAM audio tested tungsram 12ax7 tubes. If you don't know Ram audio testing, it is some of the best in the world. they also put there own ink logo on the tube and serial number on the tube that will matched the box serial number with test results very sophisticated system. These are 100% tungsram 12ax7'swith the double support getters and the tungsram "ID" tag welded to the support also. They are low noise test 100% Nos and sound incredible. You can still actually see some of the old tungsram logo under the ram serial number logo. These hardly ever come for sale on audiogon tested like this. I don't charge for paypal and hipping is $5 within the usa.
