Default Bush DAC10 capacitor query.

Hello fellow enthusiasts i am in the process of repairing a Bush DAC 10 radio. All is going well so far. I need to replace the two mains capacitors, ( cap 27 and cap 20)
I have done some research and have been led to believe I need to use X rated capacitors. I looked on e bay and have seen a Metallised Polypropylene Film MKT X 2 series 0.01mf 310 V capacitor and wondered if this would a suitable replacement?
Thanks,
Michael.

It's only C27 (Trader sheet) that needs to be X rated and that 310vAC component will be fine.
C20 (Trader sheet) couples the slider of the volume control to the grid of V3, if you want to change it use a metallised film 630v DC capacitor. NOT an X type.

Also replace C23 as a leaky one will damage your UL41 and even the output transformer.

Michael, note that the value of C27 is shown as 0.1uF (0.1mfd).
