We saw in post #3 an outline of a repair procedure for C8515 decoders. Further posts have covered identification of the Hornby parts as factory fitted. Then, more recent posts have covered a ‘typical’ tool set on the repair bench, and finally a ‘technique’ guide to removal of surface mount components with focus on the SOT-23 package.

Next up will be a set of magnified images of the repair process step-by-step. As I don’t possess any faulty decoders I used a perfectly healthy decoder for the photo-shoot. No decoders were harmed in creating the upcoming photo sequence. Yes, the decoder functioned perfectly both before and after. 

The decoder is now happily re-fitted into a Scalextric Rover SD1 with blue roof lights.
