yes, like Kevin said, i also use a defective tube on fresh sockets....i have broken a few good tubes before....i have lots of tubes that if it breaks i will not lose sleep about...
also when soldering sockets to a board, i insert a tube first to get them alinged prior to soldering, soldering with tubes inserted is good too...

I am restoring a Dynaco ST 35 that I have bought Belton sockets for and I used Russian tubes for output. The pins that are on Russian tubes are thicker, I have noticed that it is hardly possible to get the pin into the holders.
I became curious then discovered that all 7-9 pin tubes from ussr have slightly thicker pins, I took apart my sockets and opened up the upper part of the hole on the base it became much easier to put in the tubes now.

I picked up a couple of the vintage milled aluminum billet ones off ebay (shown earlier in the thread). They come up from time to time. They have slightly conical holes to ease the straightening.
I didn't know they where Mullard, I have 5 of those that I got from my father, they are probably close to 80 years old but work perfectly.
