First filter cap value selection

[makinrose]

Thanks for all the info! I Agree with you that low ripple requires more capacitance in first filter cap. As we know (and often mentioned in the TUT series) some of the feel of some of the older amps comes from the poor power supply regulation and sag that creates. I usually up the amount capacitance in amps I build that are based on old designs but then find I need to add sag resistors or SUS to try get more of a vintage feel. What circuit approaches do you favor for players who want a vintage feel but want to have nice quiet power supply?
