The chassis was badly rusted, and the audio transformers were bad, along with all of the capacitors. I took the set completely apart and wire-brushed the chassis. I also cleaned off all the shields, and brushed the copper can of the filter capacitor. The filter had dried up completely, so I hollowed it out and put a new electrolytic inside. There was a cover over the filter, which made it easy to hide the new cap. The bathtub caps were also gone, so I cleared out the tar, and hid new mylar caps inside.
With the transformers gone, I rewired the audio stages to use R-C coupling. It worked fairly good and looked good inside.
The Radiola was one of the first paper cone speakers on the market. Dad was using it in the garage with an old TRF chassis (12K7, 12J7, 50L6, 35Z5). I didn't have anything even close to the original grille cloth, so I used some red cloth. It appears purple after attempting to correct the reddish print.
Also visible in this photo is an old Westinghouse portable radio.
