Hey-hey!!!,
it's my opinion that if you're going to use SS diodes in a design that something has to be done about the switching noise. It can be done quite well, and if Schottky barrier types are used than the job gets an order of magnitude easier.

On designs which have some SS then a seperate TX is a step towards makings easier. A good Pi filter in the primary is usually enough IMO. Then I usually get carried away and go L-C on stuff like bias supplies( with Schottky diodes ).

the final call is that it is easier to make less noise in the first place, than to build a filter to deal with things afterwards.
regards,
Douglas
