put finger to keyboard and

It's polypropylene caps I guess.

There is a picture :

Any recommended source ?

This appears to be the manufacturer's product page:

Curiously, the construction is "MFP" which is Metallized Polypropylene
Film, but the datasheet for the type, B32669, lists it as "MKP", and
the lowest capacitance is 1uF.

I'd try Mouser, Digikey, Farnell, RS Components.

I'll also change the two "snubber like" 47nF MKP capacitors (mounted from the
common node of transistors and coil to both supply rails).
