Mullard UK Factory coded 6201 Military Grade Gold Pin 12AT7 matched pair!
Purchased from Kevin at Upscale Audio in 2016. I purchased the highest platinum grade Kevin offered for lowest noise levels. Further, this pair was cryogenic treated by Kevin's very demanding standards, and boy are these babies gorgeous sounding and dead quiet!
I only utilized them for a few hours (literally less than10 hrs) so they are not even broken in yet past Kevin's 72 hr demanding break in process at Upscale Audio.

Tight channel matching. Typical of Mullard UK.
I have seen these before they went out of stock at top sellers for $300/pair. I am selling this pair for $249.99. Simply gorgeous Mullard tubes. Very difficult to find any left these days if any in tightly matched NOS ratings.
I ship flat charge paid by buyer in the USA. I do not ship outside USA. I do combine shipping for one box shipment for more than one Ad purchased at the same time.
