Leak Stereo 70 amp restoration

Hi, I am in the process of upgrading a Leak Stereo 70 which I have had lying around for many years. All the capacitors on the Pre-amp and power amp boards have now been replaced with Nichicon low ESR ones and it sounds good. I am awaiting some 470uF 200V caps to replace the 500uF 64v originals. Looking on line these are still available and stated as being X2 capacitors if that is the case it would probably be sensible when upgrading to put a X2 capacitor such as 0.33uF 310v across the 230 live/neutral to take this into account. Any comments would be helpful.
I hope someone can advise on one issue of a replacement for the L1 10mH 47ohm choke which I have had to take out on one of the pre-amp boards as it was snapped in half.
I will attach photos when done.
