Fragile Center Pin
I ordered a matched Quad of Northern Electric 6SN7 for my Schiit Freya preamp. They went in nicely and they sound wonderful - However - Upon extraction the ceramic and alignment center pin int he plug unexpectedly broke off inside the socket in the Freya. I have been working with tubes for over 46 years and this is a first for me. I now have a octal tube that I cannot trust an intern to work with. It could be dangerous to plug in and easily plug in incorrectly.
