I finally got around to looking up the pin-out for my broken Tung Sol 6SN7.
Here’s a photo of unbroken Tung Sol 6SN7 GTB bases:
Thanks to some packing tape and a socket saver, I’m now using this tube in my Lyr 3.
Findings:
- The Tung Sol is way more functionally intact than some of my vintage tubes that have much better reputations. It has good definition and range, and generates no piercing whines.
- The Lyr 3’s output more closely resembles the RebelAmp now, but the RebelAmp is on another level for punch and definition.
- I should do a systematic comparison between my 6SN7s. We will see.
