Bradford console rebuild

Yes you read that right! I have used a soldering iron and have recapped a few tube amps and one Magnavox console as a retirement hobby. A family member asked if I could do anything with their old console (Grants store Bradfod line).

By default, I plan on replacing all of the electrolytic caps to try and breath a bit more ghusto into this very small but suprizingly detailed sound stage of this very under powered unit.

My observation thus far:

FM pulls in quite a few stations with solid sounding signal.
tape monitor plays well with bluetooth input.

My question is predicated on the fact that the FM signal indicator light grows dim when the volume as gained up. Is there something other than Cap replacement that may need attention?

thanks for any and all input.
