-----Original Message-----The front panels aren't actually *that* different, but they are pretty different beasts under the skin. They are both 1.8 GHz models, but the 496 was the second model in the product line, released in the late 1970s/early 1980s timeframe after the original 492 came out. (The first 496s were sold as 492s with option 6, in fact.)
The 495, on the other hand, was one of the last models, produced as late as 1993 or so.
Like the 497 that radioconnection is talking about, there were early versions of the 495 that lacked some of the features like the signal counter that were added to the later-production ones. But the later-production examples with all the bells and whistles and post-B030000 serial numbers will also have capacitor leakage problems that will not be an issue in the earlier ones.
