In Reply to: RE: RC Snubber 0.1uF 250VDC with integrated R100 resistor vs. 0.1Uf 250VACDC Wima MP3-X2 Cap posted by Tweaker456 on July 28, 2016 at 00:02:53
The real question is, why the integration of a 100r in the design of Kemet's Snubber, all things being equal? Would using the Kemet, in this application, be more beneficial over the Wima;s or will it be of little or no auditory improvement. Won't really know without trying both I know, but like I say, I'm re-upping my supply and thought I'd try the Wima's since Al Sekala seemed to be such a fan of these specifically, for this purpose, as I recall, and found the RC Snubbers on the Parts Connexion website, which caused the curiosity. Thanks

Maybe this will help. Check link...
old guy 42 or anyone else willing to respond, according to the link the resistor is to be wired in series with the X2 cap. Should the resistor be in line before or after the capacitor and what of adding a varistor to reduce start-up spike(s). The above electrical components will be added to an AC outlet that is being installed into an 1.8kw Topaz noise isolation transformer, to power my front end components.
Thanks to all.
If the signal is propagating left to right through the RC filter, with the R in series and the C in parallel, the unfiltered signal would be on the left before it gets to the R and the filtered signal would be on the right after passing the C.
You have to decide where you want the filtered and unfiltered side to be at in your circuit and configure the component arrangement accordingly.
I could place the varister before the isolation transformer and slow the in-rush current or I could place it between the transformers output and the AC receptical and slow the in-rush current there. I'm inclined to slow it prior to the transformer. Though I don't want to create a "choke point" or current limiting, though it may be unavoidable. Is there an optimal place, to your line of thinking and is there an educated guess as to how its presence will effect the sound in the end?
perform the same function of absorbing an in-rush spike and that the varister is kind of over kill? or am I wrong on this?
