I think Arran means #40, the triple electrolytics 1uf / 1uF / 2uF.
One 1uF is in parallel with the wirewound resistor 6.5K, which is in series with the speaker's field coil.
Another 1uF is T-filtering plate load for tube 75 (second detector).
And the 2uF is T-filtering with R61/R62 (right from the Filter choke rectifier's output).
All these can be plain non-electrolytic caps. With proper voltages of course.
Then you do not care about the polarity.
