Folks,
Whilst I have my MTC9000 apart, I want to replace some of the critical CAPS in the EHT area.  I can find most CAPS except for C40 which is a Polypropylene film capacitor (KP).  I can't find this type from any of the reputable sites (ebay, AliX has them but likely they will be rubbish).  I can find the value in the Metallized polypropylene film (MKP) variant.  Does anyone have opinions on replacing KP with MKP caps in the EHT areas.
Thanks in advance.
