Maplin did well - the three capacitors will have probably differed in their physical size and the arrangement of their connection leads - the person trying to help you could not see the one you wish to replace.
You may find what you need on Amazon - you do not mention the resistor values (Ohms)
Any 47uF capacitor will do - if you can get it to fit Providing the voltage specification is 30V or greater.
Be aware - electrolytic capacitors tend to fail with the passage of time - Resistors however seldom if ever fail unless subject to excessive current - if you just go ahead and replace burnt resistors the fault that caused them to burn may still be on the equipment - if there's a Zenner Diode in the circuit then change that just in case.
RS and Farnell will be bound to have the components you require providing that you're able to specify them clearly - but Amazon will be your best bet I think - no holding on the phone.
Good Luck...
