I some schematics I see that the voltage doubler has a small cap right at the output of the transformerb before the diode.

What is the use of it and does it worth it?

I got a voltage doubler powering a 50w pp 6L6 amp and I have ghost note problem and I'm suspecting the power supply.
It came from a Bogen CHB100.

How much capacitor will be best to use?

Do I really need a coil? cause right now I don't have one.

In the previous post there's a svhematics of a voltage doubler and the first caps or really big( 820uf). does it have to be that big?
