Kevin,Is there a way to explain this by example, by using Duncans PSUD II perhaps? I remember the late Harvey Rosenberg stating that separate power supplies for the front/driver stage and output stage is recommended. Would it be prudent to make the power supply designs as similar as possible? For example a full wave damper diode (6CJ3) LCLC supply using Lundahl chokes for the front/driver stage and another full wave damper diode LCLC supply for the output stage? Although more expensive, the chokes used in each power supply design would be most optimized since most chokes have a current limit. One could use 10-20H Lundahl 1673's in the input/driver stage and 4-10H chokes in the output stage (and I know you would love to sell more chokes!). I figure the time constant issue shouldn't be an issue since both supplies are using the same type of damper diode and not Hexfreds as in the previous post. The differences would lie in the final B+ voltage and final current draw for each stage.
Thanks,
Anand.
