transformer makes a high frequency noise after ten minutes when the back cover is fitted, if you leave the cover of it works fine changed the ceramic capacitors which made a slight difference, now think the transformer is over heating creating this noise.

Hi Mac,
Used to dip such things into a tin of varnish or epoxy then hang up to set - some folks suggest superglue - always worked, but these modern chopper transfomers can get really hot in normal use - just a thought, only prob I had with this set was with a S/C Shottky dual diode - Chris.
