The substitute part that I selected for C7, and C8 on the new BOM found in post 39 has a lead spacing of 10mm when it should be 15mm.

I'll post a new BOM when I find a substitute part.

Al,

It look like that the following mouser part has got the lead spacing of 15mm: 505-MKP4-0.1/630/5.

It has higher voltage rating and its size (7x14x18mm) is slightly bigger than the original speced MKP10-.1/250/5.

It will be too expensive for me to order these Wima capacitors as I already received my mouser order. However I have got a few 275V polypropylene X2-type RFI-capacitors and the lead spacing fits the board and I will give them a try.

According to Wima page, all these capacitors has got Polypropylene (PP) film
dielectric but different internal contructions:
MKP4 is for High frequency coupling and decoupling.
MKP10 is for Switcg mode power supply & audio/video equipment
MKP-X2 is for Class X2 RFI applications.
