Trafo shield for toroidal trafos: 35cm x 4cm. Bought this to reduce transformer hum on a Rega Brio-R integrated amp. This equipement is housed in a half-width case, meaning the low distance between transformer and electronics caused a small but audioble hum on speakers when sitting close to the speakers (which I am when listing to headphones).
