The addition of 250 Ohms resistance after the rectifier tube, and the use of a 122 Ohm DCR choke, prior to the Finals, are causing a loss in dynamic capability of your audio amplifier.
There is NO combination of chokes ( that I can see ) which will get you close to the 377 VDC you seem to want to use, when you start with a 386 VAC 20 Ohm power transformer, IF you seek to retain a tube rectifier.
Off the top of my head, to optimize the amp would take a lower VAC secondary on the Power Transformer. Ugh, got milk ??
