Hi.

X2 100nF : RS 210-500
X2 10nF : RS 311-1024
220uF 16v 105oC : CPC CA04933 (Startup and -5v)

Those are suggested suppliers and part numbers for best cost, but the startup 
cap you can get virtually anywhere. Best to replace those 4 for maximum 
longevity, and any other electrolytics that look bulged or where the plastic 
cover has shrunk. The -5v smoothing is 100uF on a Beeb PSU and 220uF on a
Master, best to use a 220uF, helps to curtail some speaker background noise.
Check for dry joints too, especially on the HV side.

Mark.
