I understand these are actually Mullard tubes but I may be incorrectI am having a clean out of my NOS tubes I have owned these for about 30 years and from memory they were phono grade and closely matched. All of the tubes I am now selling have only been used once for initial testing as the only ones I have left were purchased as spares. I am unable to test them sonically as I no longer have the equipment they were used in but I only ever bought and only ever buy premium tubes from reputable sellers as I am very fussy with my audio equipment and sound so they should test as NOS. As you can see I have no feedback on AA but I do on Audiogon under bpinder where you will see all my feedback has been positive including a couple of recent transactions so you can but with confidence. $20 Freight from New Zealand
