Here is a part of the manufacturers circuit diagram.
You can see on the schematic which are the electrolytics, they have a + and - symbol to identify which way round they are connected.
In your case, for C46 the cathode bypass capacitor I would think that 47uF 16v axial capacitor would be the type to get.

The capacitor which is critical and should be changed immediately if it is a wax paper type or any paper type of capacitor is C40 0.005uF which is a non polarised capacitor. This type is the sort I often use. https://www.ebay.co.uk/itm/191644809241?
