C. Piper on heat from TDC projectors

>From C. Piper's "The Technical Page", Installment #97:

"The most comon projector used for stereo shows in U.S. is probably the TDC
750 watt or a TDC 500 with 750 watt lamps.  The latter doesn't heat slides
any more than the former, because both projectors have the same fan. 
However, using 750 watt lamps in the 500 does tend to crack condensers
(which are not as well heat sinked) and burn up sockets (which are bakelite
rather than ceramic)".

And from Installment #87:

"The reason the TDC never burns up slides is that it is the only common
projector to have an adequate cooling system."
