Partmaster and 4kenwood spares stock replacement
PCB boards for approx £28.00, but the cheaper option might be to replace faulty components on the board. I've just bought a "for spares/repair" 907d on Ebay and it appears the 0.1micro farad capacitor has burned out and possibly the resistor which lies parallel to it on the board. The capacitor manufactued by RIFA is available from RS Components for about 44 pence. Unfortunately I am having difficulty reading the 3rd colour band on the resistor (green,blue,?, silver). To date have not been able to find a circuit diagram for the PCB in order to find the resistor value.
