Thanks. It is very difficult to actually get this capacitor out, as it is attached to the motor, which is not accessible without significantly dismantling the machine, but I have been able to cut the two leads coming out of it. I hoped that it was wired across the motor to reduce rf interference, and so not vital to the operation. However, when plugged back in, the motor still goes full speed, whatever the depression of the foot control (the old Elna foot control). Any other suggestions?
