Hi,
well I couldn´t detect any offense at all.
Basically most of the Technics are the same with regard to bearing and motor.
Electronics differ more in kind of chipset and drive current. If one doesn´t need the fast speed-up and breake of the discotheca models one could perfectly happy with the home-hifi models.
This is a SL-5210 like I ebayed. The SL5210 belongs to the first Technics that employed Quartz control.
While the plinth and lid showed clear signs of age and wear, the important parts like the bearing were in mint condition. I stripped it, since I wanted to give it a new look.
Fortunately the unneccessary comfort as Repeat and other automatic functions are switched by a mechanical switch. I omitted with them just leaving two functions On-Off and 33-45. Using simple FilpFlops I replaced the remaining mechanical switches by small pushbuttons.
The original power supply, a low-quality transformer, putting out way too much voltage - with associated heat losses in the regulator-circuit, was replaced by a small encapsulated SMPS.
Old Electrolytics were replaced by new ones. PCB inspected, cleaned and serviced.
A new plinth was made, from sandwiched layers of wooden and damping materials, topped by a slate plate. The wooden plinth holds the motor and electronics, while the tonearm is held by the slate plate. Plinth and plate are separated by a soft layer.
The old lid was replaced by a new one which is a replacement part for Numark TTs. It allows to play the deck with lid on and certainly looks more stylish than the old brick-style lid. Besides it was also alot cheaper

The TT-platter unmounted, was ringing like a bell. I damped it with layers of self-adhering Bitumen. worked like a charm.
As tonearm I use an old Rega RB300 I had laying around for a while.
I stripped the old internal cabling and made a new one.
Especially for MC-Pickups balanced signal transmission offers certain advantages, so I mounted balanced Lemosa and unbalanced RCA/Cinch connectors into the back panel.
Last modifikation was a new excentrical counterweight for the Rega, since my Pickup was too heavy for the standard weight.
Four simple rubber feet, left overs from a amplifier casing finished the package.
All in all the costs were lower than the appearance might suggest
