I have some Baldwin labeled 12AU7 and 12AX7 tubes for sale. The AU7's are Sylvania gray plates and the AX7's are undetermined with orange printing and say Made in Japan. All have been tested and any under a reading of 80, where 55 is good, were tossed. All test fine for shorts. All will come in white boxes with testing results written on the box.
$10 pr for either...plus shipping. Great price for tube rollers
