Wow, what an amazing resource!
Thank you for the link, as I am sure I will be spending much time enjoying the content.
That said, with regards to my initial query, I am not sure that clicking through non text encoded image file scans of product brochures for each year is much of an improvement.
The amount of information on that site is almost overwhelming, particularly with a search function that dies not seem to work :

and quite a few dead links at least regarding Altec Lansing:

Please do not misconstrue the above as any form of criticism as I know first hand that assembling and maintaining such an archive is project of love usually coupled with limited resources. I fully appreciate all of the time, effort, and care embodied in such a project. I have attempted to build archives myself and my project pale in comparison for sure.
Maybe I am lazy, but I was kinda just hoping the collected knowledge of the folks on this forum might chime in and say something like ...
"If you are looking for a green-faced Altec Lansing power amp in the 100-200 watt range check out the 1234x, 1243B, and ABCD Series 2 models"
Because sometimes asking a human is just better than asking a robot.
