Silly old me
Its been a long day, we are 8 hours ahead of GMT here.
C25 is of course the reservoir cap.
You will need to get the polarities on all these new electrolytics correct, -ve ends to all the 'bottom' ends in the diagram. I'm surprised that they are not marked on the diagram, but as it was a box cap perhaps it was originally obvious?
Are you going to put the new ones in a box? It would look more original.
Hope that the speaker energising coil is OK.
