I have a couple of radios personally using for years now giving headaches. The bush transistor radio with BF 194B, BF195C, BF195D transistors which are tested out from the circuit and ok. I’ve checked every component in a pcb but no MW. SW1 SW2 reception at all. No AM noise either but cassette, aux in works fine. Checked the transistor voltage that also ok but no radio reception. Next Philips stereo radio using TEA5711T IC. FM working fine but no MW, SW1, SW2 similar to the bush. Checked the pin voltage of the IC and they are ok according to the datasheet and replaced all bad capacitors with Rubycon ones. Still no AM reception. Checked the band selector sliding switch for any open or contact resistance. I need to fix these two radios please help me.
