Rezpak on ebay have the right coils for the job at £6.40 diy or send your pack to them £13 and they do all the work [ this answer is also on F reg with the link to ebay ]
Picked up the resistors this afternoon. Got them soldered in to the resistor base and voila:
Popped it in to Felix and it works an absolute treat. All 4 speeds - nice and slow to super fast. As always I highly recommend the ceramic resistor path... it's the way to go and it's CHEAP! Total paid £4.74.
rezpak warranty for live and they are wire [stainless steel ]I'm gonna stick with ceramic as they are much stronger than wound wire.
looks great!
Ordered from Rezpax yesterday as I did not find all resistors locally.
