SR-1050 TT issues...

Hi everyone,

I bought recently an early 70s Sansui turntable SR-1050 at a local flea market for 70€... I fell in love with the tonearm and the general wooden aspect of the whole. The seller, a passionate, told me it was a Japan import (the AC plug is indeed a japanese one, need a european adaptator). The TT works just fine with the shure M75MB there was on. I opened the back to see if cleaning was needed : no dust at all, no rust, no unsoldered wires or oxidation... and a really nice japanese conception. Just had to re-level the platter, since the rubber of the suspension on the motor side was too flattened (more weight on this side).

I really would like to change the cartridge for a more accurate one. Thought about the famous DL103, or any other cart. that works fine with this Sansui tonearm. Any Idea?
But my problem is : I can't figure out how to set the tonarm accurately. There is no graduation on the tracking force weight! + there is a lateral weight on the right I can't understand the use (not the anti-skip). It's not a problem with the already mounted cart., but if I afford a very good cart., I want and need to set it up the most accurately possible.
I searched for hours the user's manual or any info about, but only result is the service manual and brochure...

Please help me

NB: the SR1050 tonearm seems to be the same as the SR2050...

Hello skars, congrats on the tt. I have a 2050C and you will definitley need a stylus force gauge. After I balanced out the arm and set the counterweight on my table it was not accurate without a gauge. As for cartridges I have found the sumiko oyster and shure m91ed work well with my tonearm. I tried a grado black and it just didn't work well for me or the arm and that has been the extent of upgrading cartridge wise. That's not to say a grado wouldn't work with yours. It's kinda hit and miss to find the magic one. The lateral weight is a mystery to me. I put mine at the notch on the peg and doesn't seem to affect the arm's performance or sonics, that I can tell, if it's moved in either direction. Hope this helps you a bit and enjoy your tt.
 
Thanx for the help drfibes13; I purchased a small electronique gauge (precision of 0.01g) that will be very usefull... I'm still hesitating with the cartridge choice. The DL-103 looks great to me, but may be too accurate with this kind of "mid-range" TT + there is no return-exchange policy for the stylus here in France. I'm used to MM cart. (Shure/Ortofon), and I would like to taste the sound of MC cart. (I own a Pro-Ject PhonoBox II as RIAA amp., which allow MC). I mainly listen to funk, jazz and 70s rock... but I'm interested in quite everything.
I found also with the test of the strobe that my TT is very slightly too slow on the 33 1/3 and very slightly too quick on the 45. Is it due to the motor drive or to the belt? I opened the back and it doesn't seem to be anything to calibrate the motor drive...
