Any suggestions are very much appreciated:
My eclair NPR crystal sync motor worked fine yesterday and this morning a disturbing pattern began. The problem occurs with or without the film magazine.
1. sync speed for 45 seconds, wobbling sound from the shutter, whine, motor disengages and runs at 1/8 speed-
2. after 45 seconds, restart camera and the motor is normal for 30 seconds
3. 15 seconds
4. 5 seconds
The square controller box becomes hot when the motor slows-
If the motor rests for an hour or more, the cycle can be repeated.
When the motor is removed from the camera body, the problem disappears.
