So now I know...
I am very lucky; this one was kept out of the sunlight and so has no yellowing.
The precision is amazing. It is in the Que for the next shoe
The Hall of Fame
It did not come with the knee lift so this is what I came up with.
Amazing to have a domestic machine with a knee lift!
Sooo I now have the infamous "full speed only" foot pedal😒
Have to figure out what to do... I think I'm going to try a conventional controller?
Turns out we have a top notch Bernina Technician in our corner of Michigan.
The Technician at Fabric Affair gave me excellent advise and got the system running with the suggestion of replacing the brushes in the motor as a 1st order of business. So between him adjusting the sensitivity on the pedal and my replacing the brushes the machine is fully functional although it still has little bits of hesitation during start up.
