Hey Synthgods. I finally got my broken Time Modulator back. Some questions come up as a result. I'd heard that the delay line module (epoxied! Damn!) was crystal in nature, not a standard charge-coupled delay line (Panasonic and Reticon BBDs). Is there any truth to this? When did the Panasonic and Reticon chips first come into being? I want to know what's in the epoxied modules. I may end up having one broken open, just to know (and to spread the information, due to the designer's unwillingness to do so). The original design, Model 5002, has two modules, which can max out at 100ms of delay. A later unit, the 5402, added more delay lines to max the delay out at 400ms. Since there isn't room in the same box for eight of the epoxied modules, I'll take it that they put several of the delay elements in a single module. This makes me suspect that they were using standard BBDs... St. Croix, the designer, was the one who told me that the delays were crystal, and that the photography industry now uses them. Does anyone have any thoughts on that? The who, what, when and where?
