Fitting new cartridge
« on: August 30, 2018, 10:09:07 AM »
Hi

Just before I replace the cartridge on my TT I just want to find out how the new one must be fitted to the headshell nl - does it have to be a certain distance in the two grooves on the head-shell and do you need a special tool to precisely align it?

You need a protractor to set overhang and offset angle.

Have a look at some of these resources.

Vinylengine has some free protractors that you can print out and use to finesse your alignment. Register for free. Lots of other helpful info there as well.

not the easiest thing to do. why not post what TT and cart then you may be able to get better pointers.
the problem with doing it with limited knowledge is that you will always wonder if you got it all right, then you fiddle and bugger it all up.
OK well that may just be me

Ask for someone to do a proper lineup for you if you battle - there are a few guys here that does it professionally. Makes a difference.

Yup, that sounds like me too - its a Lenco L-90 and Im replacing the stock cartridge with a AT95E.  Not the best of TT's but it is a starter for me - has a straight tone arm with the angle in the headshell.

What they don't make very clear is that besides twisting the cartridge - you may also have to move the cartridge forward or backwards in the headshell to achieve alignment on both grids. This will set the correct "overhang". 

The "overhang" is the amount the stylus literally "overhangs" beyond the platter spindle when the tonearm is in line with it.

This makes me think why don't TT companies print some sort of alignment marks on the platter itself, it wont be 100% due the cartridge will hang below the platter matt but still close.

I've come across it a few times where, on some Japanese "plastic fantastic" turntables, the indicators are "printed" on the underside of the rubber platter mat. Turn it around, set up the cart using the indicators, and turn it back. Easy, and precise enough for most of those tables.

I came across this protractor which nicely explains the overhang adjustment https://www.sound-smith.com/sites/default/files/Novak%20Universal%20Overhang%20Gauge.pdf
