many older slide projectors (2D) with inoperational fan motors, and my 
TDC model 116 suffers from "slow start", that is, the motor starts out 
slow and takes about a minute to achieve its full speed.<<<<

The fan was running, but I don't know if it was running at the optimal 
speed. I thought this may be part of the problem as we haven't 
experienced this problem in the past (that I know of), and we have put 
quite a few RBT mounts through this projector. Since it melted the the 
ones with the white side towrds the light as well as the backwards 
mounted ones (just not as much), my first guess is a malfunction in the 
fan. I think it is a TDC 116, but I don't have the projector in my 
possession. Are 750 watt bulbs too powerful to project RBT mounts, which 
seem more sensitive to heat?

Thanks for your help.
