Need quiet 6V wall wart for Icom R10 receiver/scanner
 

Switching wall warts I have tried introduce a loud "hash" that
completely hides weak signals; transformer wall warts I have tried
introduce an annoying buzz -- most likely 60 cycles.

Can anyone recommend a 400 ma wall wart with cleaner output?

Failing that, How about a simple, physically small circuit to clean up
a typical wall wart's noisy output?
