The AC plug is missing so no turning the unit on for any type of checks. I will give the unit a quick survey to see if anything major jumps out at me.
Turning it over I can see that it is missing its rubber feet.
Nothing major but I do see that the bass, treble and balance indicator masks have some wear on them.
The bass and balance have bad enough wear to the point that the masks really need replacing. I will try to find replacements or print some of my own. The treble mask is in good enough shape that it could be used as a template to copy from.
Here are the Beomaster indicator lamps. I will get the receiver working again before looking at replacement options for the lamps. LED replacement is an option but some of the lamps are integral to their circuit operation so any replacement there will require more than just an LED and a load resistor.
Next step is to check my 105°C electrolytic capacitor stock to see what I have and what I need to order in recapping this Beomaster.
