Beomaster 8000: Recapping the Filter and Tone Controls Board (#4) and Broken Signal Meter

I moved on to recap the filter and tone controls board (PCB #4) that is under the control panel of the Beomaster 8000 I am working on...not much to report about the capacitor replacement. Here are pics:

Before:

and after:

Sadly, the more 'interesting' part of this board is the non-working signal strength meter. I unsoldered the contacts and measured the resistance. It is open circuit, i.e something is wrong on the inside. It looks pristine inside, from what I can tell by peeking through the plexiglass cover. I am wondering if one can open it up without penalty...I guess, we will find out soon.
