A common hack for old radios was to add a phono input. Often thats accompanied with a toggle switch. Do you have an 'unauthorized' audio jack on the back? Maybe thats it.
In that type of set ALL of the tubes should light up. With the loktal ones like those sometimes its difficult to see when there is heavy silvering on the inside top of the tube glass. Turn out the lights and look closely. Lighting up and B+ are not related.
You can check for B+ 'across' the new electrolytics that you installed. Pos on your meter to pos on the cap, neg to neg. There could be problems further downstream but thats a start.
