Have a quad of re-issue northern Electric tubes. These came with a Cary SLP 05 I purchased a few weeks ago. I was told they were a platinum matched quad (I don’t have a tester to verify this) by the seller, and I ran them in my preamp for a few weeks with zero issues. I don’t have original boxes, but will ship in EH boxes. Shipping within Canada is included.
The gold has come off slightly on the tips of the pins as shown in the pictures.
