cakyol-
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.
