I just picked up a Technics SL D3 at the local Thrift for 20 bucks. Very clean unit.
It has an Audio Technica AT84EX cartridge mounted,the needle, however, is completely missing from the stylus 
Do I need to replace the sylus with the exact original part? I believe that is an ATS13.
Anyway, the cartridge had this brush attached to it.
I'm guessing this isn't a great idea....is it something I want to use?
Seems to me it would throw off the balance or something like that.  |

| Wow. I haven't seen one of these for a long time. They were often used on the RCA Bakelite 45 players from the 50's like the ones seen here. http://everythingradio.com/RCA_45_players_for_sale.htm They were designed to clip to the side of the plastic tonearm. I've never seen one attached to a cartridge, but I suppose you could clip it to certain headshells. You could use it if you compensate for the added tracking weight with the counterbalance, but if you clean your records and stylus religiously, you really don't need it. |

the turntable is in real nice shape for it's age so i'm guessing the previous owner was really fussy about his records too, which may be why the overkill with the brush...I don't know.
I wouldn't be putting it back on...anybody looking for a vintage tone-arm brush?
You can have it cheap...maybe a swap for a record!

....OK, back to the cartidge.....as mentioned it is an Audio Technica AT84 EX (no idea how old it is)..I purchased a replacement stylus for this thing only to find out the cartidge is bad. ....I think...There's no right channel, very faint and scratchy. (This is the first time I tried the turntable .) When I move the head mount and cartidge to another one of my turntables-same thing. What's the chances it's the head mount or lead wires and not the cartidge?
Should I try the cartidge in another head mount? Do head mounts/lead wires go bad?
I'm really crummy at trouble shooting this type stuff. I always feel like I'm not trying the right things. |

| Yes, it's quite possible the problem could be in the wires. Check to make sure they are not loose from the headshell and are attached securely to the pins on the cartridge. Also, clean the contacts on the end that screws into the tonearm with a pencil eraser. If this doesn't help then I would try mounting the cartridge in a different headshell. If you still experience the problem then I'd suspect a bad cartridge. |

Ok, I mounted the cartidge onto a diffent headshell and the problem is gone.
So I can conclude the headshell and/or wires from the Technics table was the bad part and not the cartidge, which is great because I really didn't want to buy a new cartidge, this one is fine for what it will be used for, besides I just bought a new $40 stylus for it...
Now I need to pick up a new headshell. And so it continues... |

The new headshell did the trick, sounds very nice indeed.
I believe, however, that I now have to make some type adjustment to the tonearm.
When operating in the auto-start mode, the needle wants to slide ahead a couple grooves at the beginning. When I manually drop the needle down it settles in nice.
I've messed around a little with the arm-lift height and also fiddled with the auto start position adjustment screw, but to be honest with ya, I don't think I'm doing the right stuff.
Is this an anti-skating issue?
The stylus pressure is 1.5 (1-1.75 recommended with this needle)so I also set the anti-skating at 1.5
The turntable it self should be level, I haven't moved it and it was working fine prior to this.
If I set the antiskate at 2.5 it settles, but is that too high?
Any ideas on the correct adjustment needed to correct this sliding needle?? |
