Andre- Your post deserves a much more thoughtful repy than what I have time for now, but I just wanted to correct another mythical rumor: >Now then, many people have talked about upgrading their Echoplexes to the >full 198 second configuration since the beginning of the list. Until the >last week or so, however, there wasn't *one single warning* from anyone >associated with the unit on this list that doing this might have the >slightly detrimental result of causing your controls to freeze up in the >midst of performance! (This was the primary source of my comment >referring to the Echoplex as "what appears to be an increasingly >problematic unit.") The reason no one ever stated anything like that is because it is not true. None of the possible memory configurations cause crashes or problems. This particular rumor sources to a fellow who posted a review on the Harmony central site, wherein he said that installing more memory caused the unit to behave erratically and crash. I talked with him and sorted out his problems, and it wasn't the memory that caused it. His problem was the same thermal problem that I will probably be explaining to people for the rest of my life. Once again: older units have a circuit error that caused the Undo switch to execute record when the unit was hot. New units do not have this problem. If you have an older unit, the modification to fix this is very simple. You can do it yourself, I'll be happy to explain it to you. The only reason installing more simms might cause this problem is if the simms you get draw a significantly larger amount of current than the simms it came with. This is **highly unlikely** because 4M simms are typically made from a more modern technology that consumes less power than the older 256k simms that are used in a stock 12sec echoplex. I measured current draw on a bunch of simms while I was at gibson, and found the worst by far to be an old set of 256k's. It definitely was not an exhaustive test, but it is telling. In any event, this is a very easy thing to fix. Also, this is an example of what I was saying before, about the problematic nature of public forums such as this. Rumors spread quickly, yet are nearly impossible to fully dispell. There are certainly more dramatic internet examples than our poor maligned echoplex.... more later...... wondering why I do this for free, kim _______________________________________________________ Kim Flint 408-752-9284 OEM Engineering kflint@chromatic.com Chromatic Research
