This RT-707 appears to be running a little strong compared with the Pioneer factory torque/tension targets, but the difference is modest, and the Tentelometer measurements show the transport is behaving consistently. It's a little confusing because the Pioneer torque spec is from a mechanical pull and the Tentelometer test the tape "pull" while the deck is running with the torque is always changing . The AI figured the Pioneer torque spec is from a 3cm radius .
