Radios need diodes across diodes in a power supply because diodes modulate conductivity to mains wires. Mains wires work like antennas, and radio has a high sensitivity to all possible sources of a signal. So any rectifying diode in a radio power supply has to be shunted by a capacitor (about >=1 nF) to get rid of this parasitic modulation.
