Assuming this is a Technics SL-1200MK2

It's a pretty simple matter of disconnecting the switch that engages in the "center-click" position.

The biggest hassle is getting the turntable apart to do this, if you're at all unconfident about your technical abilities it's worth paying a qualified person to do it.

Mod

But would they then operate as a regular direct drive ?

The quartz makes the motor operation very rigid ( locks the speed ) when you remove the quartz you can thumb the platter w/o that much pitch bend. W/ quartz on, the platter should not be slowed or sped up because it will overcompensate in the opposite direction.

The center click just locks true 33.333 or 45 respectively.

It does make the slider operate smoothly but don't think it affects the operation...

I ask because I want to be able to thumb the platter when I play classics but not when I play current trax...

Why don't you sell your MK2's on Ebay and get Mk3's?

Hi Harry

Do they operate as regular direct and quartz ? I did'nt believe so.

I'm also a bit attatched to my 1200's have kept them in great shape. The last time I bought a new one was about 9 yrs ago and the oldest is about 22 yrs old...

Have modified and tweeked, buffed and shined and to tell you the truth I think I love them, albeit in an unhealthy way...

I understand

I totally understand your attachment to your turntables, don't get me wrong....BUT...the mk 3 has a quartz lock button you can engage, which locks the platter at 33 or 45 and defeats the pitch control. When you disengage it, there's no quartz lock and you can slide the pitch anywhere (no center click. A good innovation to an already excellent product. Every other supposed 'improvement' on it is imperceptible.

I can do that mod...

The one I don't know is the one that turns it into an old fashioned regular Direct Drive... Like an 1100a or 1200 (mk1) That would make playing classics alot smoother...

removing the actual quartz control is easy its just a matter of snipping one resistor and then if you want a switch you just drill a hole in the cabinet put a switch in and solder it to the snipped ends and voila a switch for quartz control or no quartz control

if you remove the central bypass circuit as well you will get no zero point(like the m3d/mk5) and if you remove the ball youll get no click

hope this clears this up

ill dig in my manuals for the resistor this is (for mk2)

i do not believe that snipping the resistor is necessary....


you can just unsolder one of the wires from the pitch board to disable the quartz lock bypass from what i remember...

or are you talking of disabling the quartz, all the time? and not just the quartz lock bypass...

snipping resistor tp17 on the motor board disables the quartz motor contol for the whole pitch range not just the lock

so yes all the time and not just the bypass

ps you only need to snip one side of the resistor and just lift it a bit so the contacts dont touch that way you can re mod it back if you want( or solder jumpers to a switch)

i would not recomend this if you are a hip hop dj or seriously into beatmixing house or techno this is good but the quartz does keep pitch better for metronomical electronic beats

this is for disco mixers mostly

again this is just my opinion but in that link(and ive seen that one b4) the resistor is pulled right out i would just snip it and lift it that way you never lose it

and in that link a dif resistor is removed but im gonna guess that all those are on the same circuit so lifting any of them may work to disable the quartz feedback circuit

I have done this mod to two of my decks, and am about to do it to a third. It really feels more natural when you are using your hands to get a record up to speed. It only takes 5 minutes to do. I mainly spin disco, but I do use my decks with Tractor Scratch and play techno too with no problems.

Before you butcher your decks you don't have to cut any resistors to remove the quartz lock.
You did know this right?
I can tell you the way I know if any one is interested

My Mk2's are both original but this is how I know to do it.

De-clicking a Technics SL-1200 / SL-1210 Mk2 pitch slider

These instructions assume you have a new slider or have already removed the slider from your deck

1, Carefully bend the 8 lugs which are holding the printed circuit board - see pictures 1 and 2





2, Carefully remove the printed circuit board paying attention to which way it came out - see picture 3



3, Carefully pull out the slide assy and remove the ball bearing and spring - see picture 4



To remove the Quartz Lock:
Cut the feed to either one of the pins indicated by the arrow. You can cut the track on the printed circuit board the pitch slider is mounted to or simply cut off one of the pins on the pitch slider itself.


Hope this helps, it's a lot easyer IMO and if you want the deck back to normal it's a lot less hassle. Also if you clean the track and wiper on the pitch control it feels like new again, nice and smooth.
