I meant R32 not R22 for those that purchased a 10K.

Your welcome, Hk.

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.

the PCB should have at least dual pin pitch alternatives for all capacitors.

gracious! you are right!

...but I can bend them, what's 2.5 mm between friends? 😉

Hi Andrew,

I couldn't provide that option because I had to run heavy PS supply traces underneath C7 and C8 to connect power to the output transistors.

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.
