How to repair re-cap Hallicrafters S-40A tube shortwave Ham receiver

I am repairing this receiver for my cousin. He is a new Ham operator, KM4YMG. This Vintage radio is in excellent cosmetic condition. It needed all new capacitors. The tuning cap was very dirty. I solved intermittent tuning operation using dental floss and Deoxit. Now the receiver is running well. Could use an alignment. The bands are sensitive. Listened to some crazy CBers. Great project. Nice to give new life to this classic rig.
