WTB: Amperex/Philips 12AX7 Long Plate Foil Getter from 1950’s (Matched Pair if possible)

After many successful tube rolls in my Quicksilver Headphone Amp, I have one holy grail tube pair I’d like to acquire so I can stop and wondering, “what if…” for a while at least.

I have quite a few of the early 60’s Amperex 12AX7’s labeled “Hammond”. These are great tubes, but everything I’ve read says the 50’s production 17mm long plate foil getter variants take things up a notch. I’d like to hear for myself!

Let me know if you have a pair you’d be willing to part with for a reasonable amount of money. I appreciate it!
