[rif]

Would something like this be useful to you, or is it just antiquated today? (I'm not affiliated with the seller)

OMG, do it with a PC and some software ! BTW that B&K is over 50 years old.......

Very interesting.. will have to consider and understand many many things ..

As suggested by Netlist, I have tried Scott Wurcer's tool.. works well. it's specifically developed to test phono cartridges.

 

[mahurkars]

so do cartridges have individual EM susceptibility testing?
There may be stylus quality standards too, thinking about it.

The output is very very low. But may need some certification. Need to check on this.
Thanks for your inputs.

Scott Wurcer's tool

Can you give me a link to that please ? For quick stuff I use https://www.audiotester.de/ and the Clearaudio Test Record.

Does the manufacturer of your "new" cartridge not have measurement facilities ?

OK, and what results have you got ?

 

[mahurkars]

It provides frequency response, crosstalk, 2 & 3 order harmonics.

I have Ultimate Analog Test record. Looking for CBS STR100.

Does Clear Audio has single track with 20-20kz sweep?

Hello, perhaps you can try the 1 kHz to 20 kHz -20 dB sweep track (side A, track 6). It should give more than nothing.

This cartridge is made by self and want to take it ahead hence posted on this forum and must say, got lot of good inputs and suggestions.

Would like to thank each one of you and in particular to Netlist.

Yes. Have used track 6 and 7.. it does provide the required views but the amplitude varies and not very convenient for display if we have to combine 6 & 7 track output. Individually 6 & 7 work great.

Unlike others in this thread, I know absolutely nothing about building cartridges, nor what steps need to be taken commercially to make it a successful adventure.
I'm just sharing what I think might be relevant to your build.
Carry on.

Recorded this morning.

 

[Netlist]

I like it, the sound is detailed, instruments well separated, not harsh.
Enjoyable sound.

Wish you all A Very Happy New Year 2025! 🎈🎶

Hi,

slightly OT, but since it was mentioned here:
Are there any more informations regarding this SJplot Python script by Scott Wurcer ... for example a kind of manual how to use it, or further links?
