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?
