The suspension adjustments seem a little tricky to me and it looks like it could use some tuning. I have the 7 mm long socket needed to turn the spring bolts. Are there any guidelines or recommendations to adjust the suspension?
No guidelines provided AFAIK, there's no mention of it in the (service) manual anyway.

First make sure the turntable plinth is on a level surface, then tune the suspension so that the platter is level too. It's not supposed to have a 'bounce' like other suspended decks like f.i. Thorens, but it shouldn't be too tight either. Having the arm base flush with the plinth's top surface is a good starting point.

dutchflea wrote:That one obviously has been painted and new lettering has been lasered onto it. It is true, the "10" means black in Technics land and the "00" silver. And not just for the SL-1200 but for the entire Technics line throughout the years. There are some exceptions, namely those with a number lower than 10 in the model, meaning there is no place for the distinction: SL-5, SL-7, SL-D2, SL-Q2, etc etc, and the oddball SL-1900 and SL-2000 turntables.

It might be that there has been a mistake in the factory, which in the case of the SL-1200 and SL-1210 lines would seem highly unlikely to me (however, it has been seen on other turntables like some from Thorens).
The "10" (or just "1" on armless versions) suffix was usually reserved for black versions.
However, the first version of the SL-1200Mk2 came in both black and grey.
I believe the color was dependent on which regional market the version was intended for.

The newer, revised SL-1200Mk2's was also available in black as the SL-1200Mk2PK.
The "PK" is not printed on the top of the plinth, but it is on the sticker on the back of the TT.
These were AFAIK intended for the North American market, and are not multi-voltage like the (always) black SL-1210Mk2's (there's also multi-voltage SL-1200Mk2's, just to add to the confusion).

Thanks for this great summary of features Japi !

Do you know of any parts cross-reference for these? I have a SL-1700MK2 that needs a new tone arm lift arm (the crescent shaped piece that rises when the cue button is pushed that actually dies the lifting of the tonearm). I’ve scoured eBay, Organ Donor and google for a 1700mk2 / 1600mk2 / 1800mk2 part, but no luck. I also need the feet for my 1700mk2 if you have any cross-reference ideas?

Thanks again for your very helpful advice!

this has probably been done before, but since I keep searching for the SL-1*00 model variations (and forgetting them) I figured I'd make a summary of the seventies DD models starting with SL-110/1100 and ending with SL-1800MK2. This list is about functionality variations, I didn't include weight, year of manufacture etc. I think it's pretty accurate but I might be wrong... any suggestions are welcome. Here goes:

Technics Direct Drive Turntables SL 1100 – 1800 models

SL-110 : Manual / Servo control / without tonearm
SL-1100 : Manual / Servo control / Epa-110 tonearm
===================================================================
SL-120 : Manual / Servo control / without tonearm
SL-1200 : Manual / Servo control / Epa-120 tonearm
SL-1200MK2 : Manual / Quartz locked / pitch fader / stylus illuminator / adjustable arm height
===================================================================
SL-1300 : Fully automatic / Servo control / memo-repeat
SL-1350 : Fully Automatic / like SL-1300 + record changer mechanism
SL-1301 : Fully Automatic / Quartz locked / no pitch control / memo-repeat
SL-1300MK2 : Fully automatic / Quartz locked / digital pitch / memo-repeat / auto-return on/off / adjustable arm height
===================================================================
SL-1400 : Semi-automatic / Servo control
SL-1401 : Semi-automatic / Quartz locked / no pitch control
SL-1400MK2 : Semi-automatic / Quartz locked / digital pitch / auto-return on/off / adjustable arm height
===================================================================
SL-150 : Manual / Servo control / without tonearm
SL-1500 : Manual / Servo control
SL-1501 : Manual / Quartz locked / no pitch control
SL-150MK2 : Manual / Quartz locked / digital pitch / without tonearm
SL-1500MK2 : Manual / Quartz locked / digital pitch / adjustable arm height
===================================================================
SL-1600 : Fully automatic / Servo control / spring suspension / memo-repeat
SL-1650 : Fully automatic / like SL-1600 + record changer mechanism
SL-1600MK2 : Fully automatic / Quartz locked / spring suspension / repeat play / motor-cue (knob + lever) / infrared auto disc size detection / stylus illuminator / adjustable arm height
===================================================================
SL-1700 : Semi-automatic / Servo control / spring suspension
SL-1700MK2 : Semi-automatic / Quartz locked / spring suspension / motor-cue (no lever) / auto-return on/off / stylus illuminator / adjustable arm height
===================================================================
SL-1800 : Manual / Servo control / spring suspension
SL-1800MK2 : Manual / Quartz locked / spring suspension / stylus illuminator / adjustable arm height


All MK2 models have adjustable tonearm height, however the 1200, 1600, 1700 and 1800 MK2’s have the ‘universal’ type tonearm with a rotating ring at the base, while the 1300, 1400 and 1500 MK2’s have a knob that can be tightenend and loosened to allow up and down movement of the arm.

Fully automatic models have a device to select the disc size (either manually or, with the SL-1600MK2, automatically) and the tonearm will be raised and transported to the desired spot by a motor mechanism. They can also be operated manually. Semi-automatic models have an auto-return function (the tonearm will be returned to the armrest after completion or interruption of play).

Name variations: “10” instead of “00” indicates different color (black): i.e. SL-1300 = silver, SL-1310 = black; SL-1400 = silver, SL-1410 = black etc. SL-1360 = black SL-1350, I'm not sure if there is an SL-1660 though.

Cheers!
Japi

KentT wrote:1300 and 1400 models I don't recommend. Especially Mk II models. Cueing and automation have been known issues. No parts to fix them. SL-1600 Mk II best automatic of the lot performance and reliability wise. Equal to the original SL-1200 in performance and build but not the Mk II upwards.
Just an update to this older Post- With 3D printing the part that always broke can be had for 10 bucks on eBay or other sites. I believe the 1300MK2 is the best looking table of any of the lines( my opinion- as i have a pristine 1300 :-) )

Sorry I must have missed this.

The SL-1600/1700/1800 MK2's share a lot of parts with the SL-1200MK2. So the lifter bar for the 1200MK2 (and all other 1200 versions, except the original 'MK1') will fit the 1700MK2.

The feet are not interchangeable though. On the 1200 the feet screw into the rubber base. On the 1600/1700/1800 the feet screw into the suspension (front) and metal plinth (back).

Thanks, that helps me a lot. It seems the spring suspension on my 1700mk2 remains considerably compressed, unless I have missed some important detail. My turntable was missing its feet when I “rescued” it, and I’ve drilled and tapped the foot receptacles 6mmx1 to adapt 1200mk2 feet. (I couldn’t locate a full set of the original feet). I bought an actual original service manual, but unfortunately it doesn’t have a very clear diagram on the foot and suspension assembly, hence all my dumb questions. Thanks again for all of the great info!

Hi all,
I have a sl1400 and would like to know which protractor I should use with it, and if anyone could link a printable?
Thanks!

Hi and welcome to the forum

there is a Technics arc protracor here on the site, under the Tools section
https://www.vinylengine.com/cartridge-a ... tors.shtml

That protractor uses a different alignment method (Baerwald), compared to the standard Technics setup. The result will be that the cartridge is moved all the way to the front of the headshell, and slightly twisted inwards.

If you want alignment that is closer to the original Technics geometry, there's a program that allows you to make your own 'custom' arc protractor. Check here (long thread):
https://www.vinylengine.com/turntable_f ... 19&t=16849

The easiest way to align the cartridge is to use the Technics alignment gauge, or alternatively move the cartridge in the headshell so that the distance from the stylus tip to the edge of the rubber washer on the end of the headshell is 52 mm. With this method the cartridge needs to sit straight in the headshell, so the side lines of the cart and the headshell are parallel.

You can also use a two point protractor, also available under the Tools section. I would use Stevenson.

So, plenty of options!

Hi. My technics 1200mk2 had a bad 6 board. I replaced the driver board with a diffirence board from 1700mk2. It works ok but the the start/stop does not work. The platter spin right at the power switch is on. When the it is spinning, i hold down the start/stop then it stops spinning but it spin when i release the button. Any idea or suggestion how to fix or modidify to mark it work. Thanks

You need to examine the board for differences between it and the 1200mk2 version. At the risk of sounding callous, I think this is a wasted effort, as the 1700mk2 is a superior design to the 1200mk2, so you would get better results by reassembling the 1700mk2. There are plenty of SL-1200mk2 parts available, so why end up with an inoperative SL-1700mk2 and a semi-functional 1200?

i have the opportunity to grab a still packaged 1210 mk5.
the sl1401 is my current table.
do you think that i do notice some differences with the mk5? my platter weights 2,2 kg th mk5's 1.7kg..is it better or not?

I have a black SL-1650 Japan voltage(100V AC).
So it appears SL-1650 did not vary in its nomenclature.
Just my opinion-not an expert in this area.

I have a technics sl-1300.
I bought it at an estate auction and there was no balance counterweight.
I bought one on ebay and it slides on but it does NOT screw on. this is the 3rd weight I bought and they all do the same thing...just slides on and off like a ring too big for your finger!
I am guessing there is something missing from the tonearm that would make the weight SCREW on rather than slide on and off. there is no way to adjust the weight by stopping it at the balance point and setting the correct weight.
Any thoughts whats wrong or maybe a workaround?
I am stumped. anyone that has any technics of this series from sl-1100-1600 should be able to look at theirs and see where the arm has a screw connection of some kind to allow the weight to grab. maybe you can advise.
thanx in advance. :)
