I judt finished this RCA model A 30.
I worked on the chassis during the winter and no matter what I did I could not get the push buttons to work.
I cleaned the band-switch several times and could not find out what was wrong. So now it will play without the push buttons working.
Since it got warmer here in Alberta I had a chance to strip the cabinet and apply the proper toned lacquer.
It now looks a lot better.
