We have just released a conversion for some models of the Gaumont-Kalee sound heads (Types 378,543, and 876). This conversion gives you reverse scan analog complete with the 660nm LED, and optional Dolby SRD. The prototype, which is in service in Australia in one of Don Howard's theatres, is showing consistent error rates of 1 and 2 even when running tired old trailers. I have been asked why we would bother with these old machines. Well, first of all, respect for beautifully made projectors which even many years later are still putting good pictures on the screen. Secondly, I liked the challenge and it was pretty easy to adapt our standard Simplex components which made it economically feasible. Thirdly, Kalee owners need love too.

Your responses are fun to read because they show where your hearts lie. Where they seem to lie is in the quest for quality, but that tone runs through most of the threads in this forum. I appreciate all the suggestions and offers of equipment, but I have enough to keep me busy for quite awhile. While I did say in the original post that the Kalee was done partly for fun, there also had to be at least some expectation of making enough money to justify the costs. We are, and hope to continue to be a profit making organization. While it would also be fun to tackle some of the other older machines, I fear that the return just isn't there. There may be enough SH7500's still in service to make it worthwhile, but old Western Electrics, I don't think so. (I like the idea of the disc transducer, but I think that it has already been done. It's called a "CD Player".) Another problem often is that we don't have any of the machines hereabouts which we can use for our development. We offer a large "Thank you" to Dick Prather of Portland, OR, for the loan of the Kalee. Christie's problems are for them to solve and I think that they know this. It is important for us to stay friendly with them as many of our customers want our automation system in Christie consoles, and so we must work together. In the meantime, we do have other projects in development and will certainly keep you all informed as they are ready for the world. ------------------

This is a "Yes, but," answer. Our regular RCA adapter will fit but it is quite a job to get it in there. The problem is that the exciter lamp housing is shorter than in the 9030 series. Also, there is a cast in vent slot that is in the way. Therefore, what you have to do is remove the whole sub-assembly which has the lens mount as a part of it. Then you get your Sawzall and remove the piece of metal which hangs down (it is really a light trap). Put the reader into the lens mount (using the adapter sleeve which we supply), re-install the assembly and align.The LED end, however, is quick and easy. See what I mean, yes, but! ------------------
