Thank you! I'm still a beginner when it comes to surface mount soldering
but I'm learning new techniques every day. One very useful resource was
watching IPC certified instructor John Gammel on YouTube demonstrate a
variety of soldering techniques. One such video can be found here:
I'm really impressed with your soldering technique and your scope you've
got there! I too have just embarked on a B-7971 clock build (I've got some
tubes). I don't have the modsix kit though so I'm pretty set now on using
smart sockets from Mr. Taylor at TES. I may be late to the party here

The holding force is pretty snug. I think the 7971 has a pretty strong base
but it's always important to be careful and insert a tube with straight
pins slowly. I gyrate the tube slightly while gently inserting to give all
the pins a chance to line up. Then I push it straight in without worrying

Yup. There have been 2 published versions of the PSU and 3 of the CPU
(and a lage number of intermediate versions that weren't generally
available - and this video is
Nice video. The modular construction is a great idea.
How snugly do the pins get held into the socket cups ? I was ultra-paranoid
about pin-stress so I literally numbered my b7971's for a specific
location, put the socket pins on the tube, and then soldered. Each "socket"
was customized to
