Hal,
The speed differences below are for a two and four pole motor.
Two Pole: 50 Hz: 3,000, 60 Hz: 3,600
Four Pole: 50 Hz: 1,500, 60 Hz:1,800
Those are not loaded speeds, however, 1800 / 1500 = 1.2
I mis-stated that post, it should have been 1.2 times greater than, or less
than, the speed, but

All,
Speaking of replacing electrolytic capacitors, which I am now doing on a
Fluke 845A, I found a carbon comp resistor way out of spec. It is a 150
ohm, 1/4 watt current limiter, for a 10 Vdc zener. I noticed that it had
