OK, all fears of the red button aside, it may be just the time to push it.
(If it makes you feel any better, wear a welder’s mask!)
The red button is the record key. Since most machines spend 99% of their lives in playback mode this is rarely used, so the contacts build up oxides and the volume slowly dies out. It's an amazing thing: on my Elmo it kind of creeps up on me, until one day I realize I'm all the way up to full blast on the volume control and still not getting enough Watts in the speaker. If I let it go too far, there is no sound at all.
The thing to do is turn everything off (even better, unplug it), depress the record key about 10 times and then try it out.

Steve, Good thought, and I agree with contact problem. But, on that machine there are two red buttons, or to be precise, one red BUTTON and one red KEY. The red BUTTON gives instant record by operating microswitches which are not involved in playback, so their contacts can't affect playback. It also acts as a latch to: 1. allow the red KEY to be depressed; this is the one which operates the Rec/Play switch contacts when pessed down fully, and 2. to latch the KEY in the down position when the BUTTON is released. Therefore, the required action is... Press the red BUTTON in with the left hand AND HOLD IT IN. Then press the red KEY down fully several times, its spring will return it up between presses. Say, 10 or 20 times? Then release the red BUTTON.
Switch everything back on and see what happens. Martin
