Make your own Simple & Cheap Portable Bluetooth Speaker Malc: Made a big version of this which works fantastically well when plugged into a source, but Bluetooth is picking up interference which I've tracked to being conducted along the 5V power supply to the Bluetooth receiver. Using a ferrite made no difference. Any tips gratefully received! (5P4S batt pack boosted to 50V for 200W amp + small pair of high quality hifi speakers)

The price of mainland China's cheap electronic parts, the price of Taobao on the mainland, and the export price of multiples are too far apart.
