Studio strobe repairs in Hampshire?

[kambites]

I was using my Elinchrom D-Lite RX4s today when one of them started smoking rather dramatically. It now seems to work but the recharge time is an order of magnitude longer than it should be; I don't have the right size torx bit to open it at home but I'm guessing one of the main capacitors has failed.

Does anyone know a good source of spare parts and/or a decent repair shop in the Hampshire area? It looks like a complete replacement head will be around £250 so obviously it's only worth doing if it's going to be considerably cheaper than that.
