Consistently rated as one of the best sounding US made 12AX7, the JAN Raytheon 12AX7 Black Plates is a top contender for both smooth mids and lush top end. The last of the NATO stock, one pair left, matched. Worldwide retail price for each tube is 240,-€, we offer a last brand new pair of 1962 at the price of 280,-€ as a pair.

From Vacuum Tube Valley – Issue 14:
This super rare tube was magical, it that it did everything beyond perfect. Dynamics and micro-detail were astonishing and noticeably better than any other 12AX7 in the test. It was unanimous amongst the reviewers that this was their favorite tube.
