Good Afternoon All,

        I am getting parts together for another winter project. I picked
up a Hallicrafters SP-44 Panadapter. Which I will go through, recap and
service. It will work with most of my Boatanchors. But the Hallicrafters
S-76 uses a 1650KC first IF. So I need to convert it to 455Kc. Easily
done with a 6BE6 and a crystal oscillator. Well digging through my
crystal stash, I found the right crystal. But it was used in a BC-669. So
this needs a large crystal holder. I tried to see if it would fit into a
four / five pin tube socket. But to no avail.  So the question is. Dose
anyone have a socket that they can part with. I have checked the crystal
with my tube based crystal checker. It shows good activity and is almost
dead on frequency.
