A suggestion for MM/MC cartridge manufacturers

Good call on the 420. But, I'm thinking it was something more basic.
More than likely one of these:
1. Stylus guard in place
2. Secure tone arm
3. Disconnect turntable
4. Place on clean well lit kitchen table
5. Rubber band around cartridge
6. Remove pins
7. Remove & box cartridge
8. Rubber band new cart in place
9. Screw snug
10. Leads on clips
11. Q-tip under cart body to prevent stylus/cart contact
12. Overhang, zenith, VTF- in that order
13. Repeat/check previous step
13. Secure arm
14. Replace stylus guard & secure arm
15. Reinstall turntable
Was missed. But which, I wonder?

What is your tunrtable and tonearm?

I feel your frustration. Any real hifi enthusiast has lost $ crashing a nice cart.

There isn’t a need for your request. I’m nearing 60, poor eyesight along with the other aging deficits.

The secret to a DIY cart setup is patience. Slow, deliberate moves around that little clump of expensive audio nonsense.

If one can’t incorporate include this during the process, pay to have it done.

Never had an install disaster, but enough careless maneuvers, while playing a record.

My problem was not during installing the cartridge, it was during aligning it. It was at the stage where you have the place the stylus onto a pin hole in the protractor and then arrange the straightness. If there was a dummy stylus to do that, it would have been much easier and not cause costly mistakes.
