I just bought a new Shure V15 V cartridge for my SME 3009 s2 improved.

My 3009s2imp is manufactured in April 1976, serial# 212773

I no longer have the original protractor.

I have a question regarding the cartridge alignment null points.

There is a huge confusion on the web regarding this subject!!!

Here are some of the data that I have found in various scanned SME brochures or instruction manuals:

Original 3009 - single null point at 2 2/3 inches (cca 70mm)

3009 II - single null point at 60 mm (I've also found a document mentioning two null points - 60 & 111mm early version,

60 & 115mm later version)

3009 II improved early version - single null point at 60 mm (according to two null points document mentioned earlier -

two points @ 60 & 117mm)

3009 II improved late version - two null points at 66 mm and 121mm

3009R - two null points at 66 mm and 121mm

I didn't know that there are earlier an later versions of 3009 s2 improved.
Which one is mine (April 1976, serial# 212773) ?

What null point settings do you recommend for it?

Thanks in advance,

Aleksandar

PS I also have lost the original 1/16" hexagonal wrench.
Where can I find one? Here, we only have tools based on metric system...
