I've looked at loads of Tektronix tube equipment and have yet to find any where wires to tube sockets are not just passed through and soldered. These units stood (still stand) the test of time. It's a matter of skill. On the other hand, a poor connection that relies on a mechanical crimp is, in my experience, just waiting for a few heat/cool cycles before becoming one of those frustrating crackel / pop issues in an amp. Right heat, solder, time = good connection. Now, that being said, today we have these moster connections to make like to massive speaker terminals. That's really hard to do with a tiny iron. Get a good 'ol Weller Soldering Gun for that stuff!

He didn't say just crimp, he said hook, crimp, then solder.

I agree about the tiny iron, but NOT about the gun. I've had guns fail on me doing exactly those kind of connections. I bought a 60 W. Hexacon iron and it gets some pretty heavy duty jobs done.
IME, soldering guns can be good on tube sockets and terminal strips. FWIW, I prefer Wen to Weller, when it comes to soldering guns. Weller copper tips are a short lived PITA. Wen tips are iron and they LAST.
For truly monstrous soldering jobs, follow the provided link. Get ready for sticker shock.
BTW, before PCBs became commonplace, the construction standard was that the unit worked, without solder. Excellent mechanical connections were made, which functioned well electrically. The solder was used to lock the good mechanical connections into place. 60/40 Sn/Pb is fine under that regime. As soon as the possibility of signal actually flowing through solder entered the picture, 63/37 Sn/Pb eutectic or even fancier alloys became necessary.

If you want a heavy-duty iron that will last and doesn't cost a fortune, buy the Weller 100P. They can be had for $65-75, and they'll solder almost anything. Much better than a gun; it'll last for years, even if you leave it on all day at the bench.
