Any reputable service tech can replace a bulb and service your machine. It doesn't have to be a Pfaff dealer. If the bulb has died, you most likely need the machine to be serviced anyway. If you love and use your machine, and want to keep it running well, have it serviced regularly. My Pfaff dealer is 200 miles away also. I call ahead and make arrangements to have it serviced while I shop locally, and pick it up at the end of the shops works day. Well worth it to keep my 7570 purring!
