Nine (9) NOS/NIB RCA 12AX7A/ECC83 tubes, with grey ribbed plates and O getter, in original boxes & sleeve. All tubes have a CV date code indicating a manufacture date of March, 1970. All test like new on my Knight emission tester.
Orange print is very good, possibly with minor wear due to removal from boxes for testing. Boxes are crisp, albeit somewhat discolored from storage.
Asking $20 per tube. Buy four or more and shipping is free (and you get the sleeve(s)); otherwise $5 for Priority Mail.
