I have 2 of them. Whatever version of the 1200's I have, I know they have a built in phono stage.
Unless they are custom built-ins, you are mistaken. You can even Google the entire WWW universe and you will not find any instance or mention of a built-in phono stage for a Technics SL12x0 series DD turntable. The Audio Technica copies, however, do have them.
The AT copies have a defeat switch for the internal phono preamp. I can't imagine a turntable with internal phono stage that wouldn't have a defeat switch. The advice you were giving the OP indicates that the turntables you're thinking of don't have the defeat switch.
#1: Any Technics SL12x0 series with an internal phono stage would be an after-market modification.
#2. Check again. Your assertion flies in the face of all available info about the Technics SL12x0 series DD turntables. If yours truly have a built-in phono stage, pictures please.
There are many articles out there about orienting new owners to the SL1200. They usually go into detail about making sure your receiver or integrated amp has a phono stage.
