@Matt P I don't know of anywhere else around the north-west.
The CD63 is a nice player so you could see if Wilkinson's could fix it, they have a good repair service (generally for slightly older kit with caps, resistors, valves etc not new stuff that's all integrated circuits) but they are usually busy so turnaround may be a few weeks.
Also, with the low price of formerly top-end players (I recently picked up a CD63 MkII KI signature for about £50) it may not be worth the cost of repair, sadly.
