I did a quick PSUD2 analysis of the 'before' and 'after' power supply, which confirms the drop in B+ voltage (somewhat surprising to me). The transient behavior was about the same (well damped response to a change in current draw of from 100 to 120 mA), but there was considerably more ripple in the low DCR low H configuration. Whatever is going on is not obvious from the simulation results.

However, your 'experiment' is not really valid because you changed so many variables - differnt caps, added bleeder resistor, differnt supply voltage, etc. Maybe the improved response is primarly due to the better transient characteristics of the ASC oil cap as compared to the orginal electrolytic. I know, who cares - if your happy with it, stay with it.
