It is possible that there may be a problem with the capstan motor windings that are powered when the tape speed switch is in the 7.5 IPS position.So I am back to the same old question: Why is there a difference between the two speeds? 3.75 IPS is correct, (around 3000) but 7.5 is slow, (around 2625). There is no drag, everything has been cleaned, lubricated and lubricated again as well as trying a new belt and start / run cap. I also used jumper leads to jumper across the speed switch contacts in a troubleshooting measure to eliminate them. There was no change.
