Perish the thought! First of all, cases don't cost that much. Second, any retrofit for a case not made for it would not be as good, unless you made the board exactly the same size and shape of the board it replaces. Third, there are only so many demodulators in the world, though they are not as rare as ,say, an Audionics Space and Image Composer, It would be a disservice to future quaddies (who might not even be born yet) to destroy perfectly useable or repairable demodulators such as the 4DD5, which is a very good demodulator in it's own right. You yourself should retain one of these demods in case the Lou Dorren unit fails, for as the years go by, some parts will not be availlable, and you may need a fallback. The older demods have mostly discrete components, and hopefully parts will be availlable for years to come. Broken demods should be retained if for nothing else, to provide parts for fixable demods. Such would be the case for a demod with a cracked board, or a burned up power transformer, or a bad mode switch. As we all pass from this life, we will release quad recordings that people will want to hear. They will need something to demodulate them. Unwanted true quad gear, even broken gear, should be sold on Ebay, rather than being discarded, so that others may enjoy quad. This is especially true with decoders and demodulators and tape recorders. A quick check on Ebay reveals that CD-4 demodulators are getting more expensive, indicating increasing rareness. As time goes on, we will not be the only generation to enjoy this "failed experiment".
