I am thinking of using an AC line Filter Module on the Secondary of the Power transformer of a Preamp. This will be in addition to a Filtered Power Entry module on the AC Mains. I plan on using one of those PC Board mounted low Current (2Amp)AC Mains filter module on the secondary of the Power transformer Prior to the Rectifires. My concern is would This be as good as a Discreet component Filtor made from Larger Capacitors and Inductor Than that used in the All ready made Filtor Module? since the Transformer Voltage on the Secondary is alot lower than the AC mains voltage a Filtor Module is designed for would this would be a concern. TIA PPL.....

Hmm... This idea is starting to look less attractive.
