About 2 weeks ago i found this Pioneer Pl-12D in a dumpster near the local Goodwill. Hooked it up today, but alas...hum. I did my home work again. This time i soldered a solid RCA shielded cable straight to the terminals connecting to the tone arm wires. Mains cable directly to the little electronics board.

Hum gone! This is the quietest Pl-12D i have ever heard and i have fixed up about 5 Pl-12D's already. With a headshell with a fine vintage AT cart this free vintage T rocks!

  Back in the 1970s when I had one of these new, that overhang checker got me in the ball park for mounting the cartridge. Seemed to work just fine, but that was the 1970s, I was still in college, and the Pioneer was my first decent turntable. I'm not sure anyone used a protractor then, either, certainly not among any of my acquaintances. (I used a Shure M91ED cartridge--they were everywhere then. Not expensive for the time, and a terrific tracker.)

    My experience exactly. I remember the arm was able to use an m91ed near the low end of it's vtf range without audible mistracking.
    
    If the overhang checker was a finer line and a longer arc, it could be quite effective, I think. Not a bad idea.

  My dim recollection was that the overhang gauge worked OK. Of course, way back then setting up a cartridge for me was affixing the cartridge to the head shell, connecting the leads, and a quick run at a protractor and then let it rip! Ah, the good old days.

    I call it the "hangover checker" haha. I prefer my protractor...
    
    I found out phono signals are finicky, you need a good shielded cable or it will pick up hum.
