These guys are just confusing the issue.
I've had quite a few duals and I might even have had that specific model earlier on when I didn't keep track of what I got. It likes like a good one! If all the controls are working well, it is an excellent entry level turntable. Duals can be a little complicated so make sure the controls all work smoothly without hesitation. The 2 big things that can happen is the Stuerpimpel has disolved with age, or the grease hardens up and that requires someone with good small mechanical skills to remove and replace with the right types of lube. Ask him to remove the cartridge and put it back in during the test. The handle of the headshell acts as a lever to allow the headshell sled with cartridge to fall off into your waiting hand. The reason you want him to remove it and then to put it back, is you want to see how difficult it is to get good electrical contacts between those parts into the headshell. Test drive afterwards to evaluate. You want to hear both channels. The sled goes flakey sometimes with age and misuse.

I have a Dual 1237 that I use in my work office. It inputs to a Proton D940 receiver driving a pair of Smaller Advents. The 1237 is great for this because I can stack 6 records and listen for a couple hours. Sounds fantastic and works flawlessly ( after some work of course).

So I picked up the Dual 1237 - It had been serviced, cleaned, re-lubed, new belt, and certified completely functional with a new Audio Technica needle installed. It is 100% functional and sounded amazing at the guy's place. I got it home, hooked it up, and am getting a hum. When I mess with the RCA cables, I can make the hum go away - so it seems I may need to change those out. But all in all, I am super pleased and excited. It looks brand new. Is there anything else I should do or look for regarding the hum? Thank you all for your input.

All of the contact points in the signal path need to be spotless from the notorious black oxide. This includes: cartridge leads inside and out (i use a toothpick to clean them inside) the contact pad in the head shell including the ground contact behind the ground contact, the tone arm wires are fixed to the mute switch...this area must also be spotless. The rca cables may go to female rca jacks that need cleaning or on spade connectors under the mute switch cover....clean it.
I use metal polish to remove oxide, then clean residue with isopropyl alcohol and deoxit. It is 10x faster than using an eraser or deoxit alone.
If all else fails replace the rca cables.

And it really does still look nice. If you're happy with the sound of the AT3600 in general, you might want to consider replacing the installed ATN3600L by an ATN91 or ATN91R, though, as these two can operate at a lower tracking force.

The 1237 is a nice table. It’s one of Dual’s earlier belt drive models and I’d argue the tonearm and build quality share more in common with the quality idlers than they do with the cheaper plasticky belt drives Dual was producing by the close of the seventies. Glad you’re happy with it!
