Default capacitive input

Originally posted by SY

if you use a capacitive input filter following the rectifier, the winding's volt-amp rating should be halved.

So what's the solution? Not using a cap after a rectifier? Or using a smaller value as speci9fied in the datasheet (0.1uF - 0.33uF)?

My plan (for the moment) is like this:
trasnformer 6V secondary -> rectifier bridge -> filter cap 1000uF/16V -> two 7806's, inputs connected, middle pin to the ground -> each output with it's own filter cap (100uF/16V) -> filaments, each 7806's output to his tube, common ground.

I've found a nice heatsink for two chips and the rest is to be mounted on a terminal strip.

Have I got something wrong?
