Re-capping a 49-1601 which is transformerless.  

Uses a voltage doubler power supply with a 50X6 rectifier tube and a 20uF input capacitor (C101).

The diagram shows positive (+) connected to one cathode and one anode and the other side of the cap to power line.

Parts list shows 400v/20uF.

Now, from my understanding of doubler supplies, this cap should be NON-polar, which could be internally two 40uF connected "back to back".
But the schematic I have just shows one cap, polar.

Does anyone know more about this?
