I received the replacement buttons and decided to launch into a day of soldering. After an hour of unscrewing basically everything to get to the front panel PCB, I found the culprit to my woes ...A tonne of cigarette ash. The keyboard stank of 30 year old ash.
Cleaned the machine out (I found matches too!! God knows how they got in there).
Now the buttons work reliably.
On the other hand, the power supply board capacitors have all leaked. Will definitely need to change them soon.
