The values of caps is not that critical.Usually the manufacturer made the capacitance as small as possible because back then they costed more than today. The next higher value in cap and the same or higher voltage should be ok. eg. 34ufd 280v ,a 39ufd 350v would be fine. just go higher in cap and working voltage. These days caps come in standard values(same values)as resistors.(39,47,56,68 ect)Just use higher value of cap and voltage and you should be fine and be careful!
