So it begins!

Cool! Do you know how to interpret the codes on these? I see "F 5" on yours, mine has "N 4." Are those codes for manufacturing dates?

At 26 hours burn in, Psvane 6SN7-SE is getting scary good.

At 42 hours, playing some newly acquired Euro jazz. Kick drum really kicks, bass has both heft and subtlety. Trombone and trumpet, including breath effects: lots of detail, texture, density. Cymbals have well-defined leading edges, their multiple vibration modes surge and decay properly. Comparing with the Ken-Rad VT-231 -- already a very good tube -- upper bass and mids are more present and complex timbres are better delineated.

I haven't found too much on the codes, but it seems to be generally accepted that the 4 is 1944 and 5 is 1945. I haven't found anything on the letter code and whether that's for a lot code, a calendar month or some other meaning.

I don't get it. I must be too young.

Yeah, that's one possibility. Not the most likely one, but if it makes you feel better, then we'll all just pretend that's it.

I've been too busy listening to music. The Ken Rad vt231 black glass is a close cousin to the WH-D, and I've enjoyed comparing the two.

Same here, enjoying my still new-ish Psvane 6SN7-SE. I probably should go back to my Ken Rad to firm up comparisons, but there's an special openness that I'm really enjoying in the Psvane.

I have 3 Frankies +1 Frankimposter. Far from hoarding.

While BC may not gush, I will. Consider the Frankie a 6SN7W Tall Bottle for 1/10th the price. The W is the best tube in my stash and the Frankie may equal and even slightly surpass the W. It is really that special.

While there are lots of 7N7s, the Frankie is rare and well worth the hunt.
