the component is available from cricklewood electronics at a cost of £5 to £8 i have replaced mine and put a much larger heat sink in place and the unit runs fine, if you decide to do the repair your self make absolutly sure you carfully discharce the 400volt electrolitic capacitor if you not sure find someone to do the repair for you, as this component can give a nasty shock!!
