RE: CLC / Snubbers

According to my sim, the original Cit II PS has a significant impedance bump around 25-30 Hz. That's due to the factory values for the choke and reservoir cap. Making the reservoir larger mitigates that issue. Anyway, this is very different than what I thought you were describing when you mentioned adding a hash filter. The model I posted is valid for that, but it doesn't include a large smoothing capacitor (reservoir) afterwards. I might have to bite the bullet and take the same approach in my rebuilds. The 500mH chokes will work if I do that, it's just a matter of adding enough output capacitance to push the resonance bump to a lower frequency. Good discussion, thanks!
