I've got a 1 KVA filament transformer wired as a parallel AC filter. Choose the biggest transformer that will remain quiet, and be sure to use a circuit breaker or fuse in the primary circuit.The secondary has to be loaded to keep it from ringing. This is done with an R-C network, so the higher the secondary voltage, the smaller the C required. The transformer will absorb AC line spikes, so you do not need X-rated capacitors.
This is similar in concept to the first two stages of the JR filter, but there is no power delivered with it. It absorbs AC line noise as a parallel filter.
