7 Telefunken ECC83 tubes, these have been used for 60-80 hours on my Mcintrosh C20 preamplifier before selling. Purchased sone time in the mid to later 70s they do not have the stamped Diamond between the pins. These come with the original matching code boxes and the codes on the tubes match as well. Printed underneath the ECC83 is 70015, on the rear these have two 3 digit codes stacked I used a jewlers loop and these all seem to have the matching 2A1 & 71B codes although it is nearly impossible to read all of them. I have tested these on my Eico 635 tube tester, it is not the most elaborate tester but has been very reliable when I test a New high grade ECC83 or 12AX7 tube I expect to read a value of between 68 & 70 where the minimum good is 45. I have tested a few in the past at 72 but they usually are not well ballanced. The readings on these tubes were as follows, 68-68 , 66-68 , 67-68 , 67-67 , 68-69 , 68-69 , 68-68. These are very well matched for strength and ballanced, nice tubes.
