1 GI Brat 12 months ago I have a question about restoring/preserving old speakers. I have a 1962 Silvertone Model 1457 guitar with it's little built-into-the-case amp and speaker. It's all original (the case and amp, at least), and of course I would like to keep it that way, but I also want to be able to play it on a fairly regular basis. Is there anything I can (or should) do to the speaker to keep it working like it should? The cone looks VERY brittle, and it IS 50 years old. It works OK, and sounds amazing, considering. I would like to keep it that way. Anything I need to do to it?
