1 Sylvania 12AY7 NOS Long Plate tube.  This is the strongest testing 12AY7 tube I've ever seen, and both sides are perfectly matched.  They each tested 60 where 48 is considered new on my TV7 tester.

This is not branded a 6072, but it is exactly the same tube as Sylvania's 6072 tubes from that time period.

This would be a great tube for your DIY microphone.

$55 plus shipping to your location.

P.M. me if interested.
