I am using it to play midi files thru a sequencer programme {cakewalk}via a
sound module to an amplifier and speakers.
When using power supply there is loud RF noise. Just using internal battery
no RF noise.
Works okay with a borrowed Toshiba.
I noticed the Toshiba has a bigger transformer and maybe has an RF filter
inside.
Is there an RF filter in the Armada transformer? If not would an RF choke
solve my problem ?
Thanks for any help.
