Oh gawd. That story of the Typhoon.
It went something like this...
What's the wire for? It improves signal to noise...oops, what went wrong?...autopsy on a Rokraft 20 Navy...just leave the original wiring as supplied but insert a 22Ω or 47Ω resistor & shunt connect a 100nF capacitor just in case ...oops...send the replacement doodah back for investigation/repair...check here & here with an ohmmeter...the cap fell apart when you touched it?...ok replace and fit a 22Ω or 47Ω resistor & shunt capacitor or whatever.
...the end.
Forget the resistor if it is too fiddly.Just use the lowest suitable main fuse. That should do if you avoid a fault path through servo cable.
A fuse worked in the case of the coffee grinder,the electric carving knife,the document shredder.
No harm done. Just 2p failed polyester capacitors had to be replaced by 20p class Y capacitors and the items had a new lease of life.
This issue is a bigger scandal than crummy smartphone screens but I'm not taking a 5 year old kitchen appliance back to a shop and showing what the Maplin catalogue says in the passive component section.
Goodnight and see you at Bournville, Barrow or Leamington Spa!
