I have been reading many topics about modifying your SL-12xx direct drive with external PSU and regulators.
Since i cant make boards myself and i think the ready made stuff that some firms and good hobbyists put out on the market are too expensive.
This was the solution for me.
I have used this for the last year or so

http://www.ebay.co.uk/itm/High-Voltage-Adjustable-Regulator-Module-Based-TL783-/150765205826?pt=UK_Mobile_Phones_Communication_Radio_Parts_Accessories&hash=item231a4e7942

i took the transformer out and used it.Then the regulator module and some 4700uF caps i had after.New Van damme screened cord an desoldred the bridge and two caps,fitted it to the board,set the module for 30V and bingo!
Works like a clock.Measured 30,5 for about 10 hours ,steady as a rock.

You can also use this

with a toroid 2x9V connected to 18V to get 18-25V (Yes the technics can run from 18-25V as i have been told by Fidelity audio) and use it insted of the internal regulator.just remove the caps and resistors and the internal regulator as done in this thread.

PSU for Technics 1210

and solder the + - cords where the C3 used to be.
Set the module to about 21-22V and there you have it.
these modules comes free shipped and cost 13-26£.c
just add some transformer and caps and you are ready to go.
I doubt that they are any worse than the overpriced stuff you can buy from so called high end modification firms or persons.
It works perfectly belive me.
Good luck.
