Greg, I believe the 330 uF is the second filter cap after the choke. The first filter at the rectifier cathode is the 47 uF.
It might be the two diodes are zeners to drop the voltage for the screen supply of the output tubes or B+for the 6SN7 input stage. There are two small 22 uF 450V radial caps nearby.
The filaments are run off AC directly from the power transformer.
