Yes absolute sense especially as my patient searching just found similar information on an old thread on StereoNet Australia of all places!
Apparently the aussies love these things, likely because they will play upside down.... (jk before any angry Ausmen get all wound up!)
Unfortunately as the original excellent mc cart is near unobtanium and I could not find any aftermarket p mount mc carts it will be wearing an Azden YM-P20E for now. So I will just select MM and feed it into my regular mm phono stage.
This was the quote I found, and then a few more posts after it expounding on it a little more
"By the way, the Technics SL-10 doesn't have a built-in MC phono stage or preamp. It's a head amp/pre-preamp; gain stage only, no R.I.A.A. re-equalisation."
