Phillip, many years ago I installed Dolby Stereo in your cinema. I was a very young and green engineer in those days When is came to fitting the stereo cell I made a 'schoolboy error', for anyone who's not familiar with the solar cell for a GK21, it has the slit on the cell face, as the optics are a cumbersome reverse scanning design, I seem to remember involving prisms and other forms of light bending witchcraft...
Well to young and uninitiated, that slit looks awfully like the L/R division on most other SVA cells... Could I get this soundhead to line up? NO! Yet flick a torch beam across the cell and I got *THUMP* from the speakers. After much sweating, stressing and a good deal of swearing I finally made a phone call to one older and wiser than I, who asked if I'd got the cell the right way round. The penny well and truly dropped and I felt a right fool! Turns out aforementioned older and wiser man had done exactly the same thing some years before me, hence he took a very educated guess at where my problem lay and was able to point me in the right direction very quickly
Even further back in time I ran many a movie on GK21s and GK19s, they were getting really old by then but still kept on running. Like every other piece of British engineering from the post war period, they were utterly incapable of retaining lube oil, so a baking tray was a common thing to be found on the projection room floor.
