As you can read above, GregK got Covid really badly. Thankfully he survived, but he's not offering his extremely generous chip repairing service anymore. No-one in the UK slot car community seems to have the necessary PCB skills, the time or the inclination to fill Greg's shoes. Although there may be some local repairs going on at digital racing clubs - you could contact one near you.

The person you're looking for doesn't need to be someone in the slot car community. What you're looking for is an electrical engineer who repairs PCBs. You'll be paying for their time (significant) and replacement parts (negligible). The labour cost for repairing a digital chip may be more than the cost of a replacement chip. Greg's service really was extremely generous.

As prevention is always better than cure, please read my post above. My fried chip count remains at one - mostly thanks to following that advice.
