Unfortunately, there is always a part that is unobtanium. In this instance, the previous owner / operator decided to clean the speaker panel with steel wool or similar. What an idiot. So I had to source a better speaker panel (from my own personal game) to replace the badly scratched one.
Time to restore the speaker panel assembly.
Strip all the parts and sand back the rear of the panel.
Replace the felt - which is just "beer seal"..
New Display..
Job done - looks better !
A huge improvement..
