Default Back EMF - suppression components

I've bought a DC steam loco new and intend to fit my own sound chip from youchoos - probably MX648R for ex LNER J15. As I understand it, some Zimo chips have issues with the suppression (capacitors) which monitor the back EMF (I think my understanding is correct) and the advice I seem to be reading is simply snip them off.

Questions are: Am I right? Is it that simple?

Flashbang will become famous soon enough

Removing the RF capacitors will not cause any issues when using a DCC decoder.
Personally I would try the loco with them still in place and only remove them if problems with motor control follow.
Broken? It was working when I left it!
