I have replace the 2200uf cap. between the two plugs/sockets on the Audio pcb and now the FM works fine, with a small amount of background hum, so I may also replace the 3300uf cap., but there is no sound from the DAB band, although the display and tuning seem to work as normal. Would replacing the 1000 & 220uf's mentioned by John cure this problem, or is there another possible cause?
