Jon,

I'm out of pocket today, but I will take the CBS 12ax7.  Remind me again what the 5814 is closest to?

Plus bump for a great seller guys!

5814 is closest to 12AU7...it has .3mA??? more heater current? The E80CC has .6mA more IIRC. Can't remember.

Pretty sure I still have the CBS 12AX7 ...will check at lunch.

The CBS 5814 is not gold pin, my mistake.

If you want to call me at lunch, I can tell you about the two pairs of 1957 square-getter wing-plate RT France 12AU7 which are pretty rare. You might have one already though.
