So I recently did a re tip of an Acutex stylus with a Shibata tip and also an Entre' EC-20 with an generic elliptical.
I wanted to see how well I got the azimuth right of the cantilever/stylus assembly . Listing and visual inspection can only go so far. So I thought i'd finally pull out my O'scope and put it to use
on my Acutex re tip. Before I pulled out the scope I wasn't happy with the alignment so I re did it a few times ( you can adjust the alignment a bit on these styli ) till I got it as best I could with visual inspection.
First let me say using the Analog Productions test disc right after the initial re tip left the balance to be desired. It seemed way off. after a few re visits tot he work bench it got much better but I am at my limits adjusting the stylus assembly with out removing the cantilever and doing it over. Have not tried to remove super glue before on a stylus and not sure I want to with the delicate suspension components right there to be exposed to the acetone.
So now to the three O'Scope pictures I took. Its not to bad. A little louder right channel but nothing you can tell and with an adjustable head shell you might be able to dial out any imbalence , I'm testing on my AR XA . no adjustment for azimuth here. But I do have to re visit with different VTF as these Tri Pole designed carts
are fussy to VTF and channel seperation .
First is both channels with a 1 kHz sine wave. .2 volt/div and .5 sec/div
here is the left channel signal only and the right crosstalk below , not to bad I think.
And the Right signal with Left crosstalk.
Pretty cool I think.
So what else in Cartridge set up can you do with an O'Scope guys?
