I am new to the world of valves. Will this socket fit a 12AU7/ECC82? Its hard to tell from the drawings.

Yes, the 12AU7 tube is a 9 pin miniature tube so it should fit perfectly.

Looking from the bottom of this socket, where is pin number one? I am building the Bob Heil pine board project and I want to make sure of the correct pine placement for the 12AX7.
Please advise.
Thank you

Looking at the 3rd photo in the parts information, (the gap in the pins is at 6 o'clock) the first pin is going to be the pin directly to the left (approx 7 o'clock) of the gap.

Good quality materials, but the ceramic base is in two layers, loosely joined by the centre post. OOPS! This is true of a deferent socket I recently purchased.
It solid and very well built. It requires a 7/8" chassis hole. There is no way to get it into a 3/4" chassis hole.
Great product
Ceramic , so it can take the high temperatures of 6BQ5/EL84 . Picture makes it look like one piece , but it's not , the metal ring can be moved to the bottom also , making it a top or bottom mount.
