Yeah, except that the infamous "Dual hum" tends to be channel-specific -- in the left channel, I believe, though often faint. My Dad's had it on his 701 for 40+ years, and he's very competent electrically. He's never been able to track down the cause of the problem.
If it were just an issue with the headshell connectors, you'd expect a more-or-less equal frequency of noise problems in both channels. But in this particular case...
Soldering connections may seem like a great idea, until you snap a lug. If you're lucky, won't have to replace the whole mounting sled, since you no longer have the option of simply pulling off the broken wire.
"...only reliable Dual repair person..." I'm trying to think of how many problems I've caught that so-called Dual experts missed. Good thing I don't charge me anything for my time.

And I cannot tell you how many of 'some other guys'' repair jobs I have had to re-repair.
