Folks,
Well, this weekend, I started playing with my Technics SP-15/AT 1005. In a previous thread, I had asked about which headshell I should use, since the original headshell is unusable due to shipping damage. I picked up a cheapo Stanton plastic headshell at my local Guitar Center to get started.
I tried several different carts (Grace F-9, Shure M-95HE w/JICO SAS, Denon DL-300, Denon DL-103S) over the weekend. While switching out carts and setting the arm up for them, I discovered 2 things: 1. The string was glued (!??!?!) to the bias arm and not looped as it should be to allow adjustment; 2. The anti-skate bias weight is not all there.
My first concern was rectified with some fishing line. I cannot believe what a PITA it was to get the line fed thru that tiny little hole on the weight. One piece of advice here: use an angled cut on the end of the line you put thru the hole!
However, the 2nd issue is not so easy to fix. The bias weight is supposed to be a 2-piece affair. The main weight is used to provide anti-skate bias for VTFs between 1 and 2 grams. The second piece screws together with the main weight and provides anti-skating bias for VTFs between 2-3g. I do not have the second piece though and I'm not holding out hope for finding one.
So, my question to the assembled masses is: Does anyone know how much the second piece weighs or what the combined weight is supposed to be?
My hope is that the combined weight will be similar to an available bias weight that I can just purchase. The other option is to get the auxilary piece fabricated.
Oh...and before any of you wise guys jump on me; yes, I know that none of the carts I've used require more than 2 grams of VTF. However, I still have an Ortofon Salsa (VTF 2-2.4g) and a Benz Glider M (VTF 2-2.5g) to try out.
Thanks!!!
Jeff
Follow Ups:
I asked that question before....Here is the link of the guy who answered me...with pics. The weight is 2.2gr and the second part is 1.8gr for a total of 4gr
Hi1.7 & 1.7=3.4g is only my assumption (so that my simulation might be wrong).
The link at Lenco as indicated 2.2g(main)+1.8g(sub-screw)
sound "more reasonable".
I commented in my excel sheet: "Bias scales are not linear as seen from the centre of pivot. Hence even if bias weight is made as light 2.3g/heavy 3.1g, IFC scale cannot cope with IF linearly."Thank you for your link at Lenco.

Each part of the original 2-part bias weight weighs 1,7 g.
So 3,4 g combined. :-)
See the AT1005II info at the bottom of the page in the link.
Rgrds.
Thanks a bunch!!!!!
