I'm going to watch the results of these sims be hashed out amongst the group here... and enjoy Dave and Chris' bringing simulations to the table...
I'd just like to point out that it'd be next to impossible to speck a choke at 1.1 henry, vs 1 henry... that has to be an error on jeff's part in the sim.. I can't imagine that .1 henry difference making a significant difference, just know that the chokes will measure differently under different current levels and that he couldn't speck two difference chokes, one at 1h and one at 1.1h.
Jeff we've had debate over different chokes meausuring differenctly...using a LCR or a real bridge, etc.
that is the main probelm with tuning in PSUD2 to these extremes...its difficult to get an accurate indutance on the chokes, it is all guess work.
on another note, I'd still stick with the two 1h chokes and believe Dave's simulation shows lower impedance across the board, albeit with the resonance around 50-60hz... which might help dynamics :)

Rage,
I wonder,..... what if one 1 HY choke is wound with 10% more turns than the other, and maintains a similar gap?

Out of Depth.
from my limited experience inductance doesn't necessarily work that way.
is this extra .1 henry essential to your tuning?
"from my limited experience inductance doesn't necessarily work that way."
Indeed. The inductance goes like the square of the number of turns, so an increase of 10% in inductance would be achieved with roughly a 5% increase in the number of turns, not 10%.
