I blew up my 5i25 board

I believe it has been turned off.
my email (in sort of longhand) is eric dot gunstone at gmail dot com
hope this is acceptable on the forum

To follow up on this, I purchased some FST1621MTDX 24 port digital bus switches from Mouser at a cost of 4 for just under AUD$12 with postage of AUD$24 (ouch!), and sprintertrd (Steve) offered to replace them as he has much better gear than me.
I took them to him today (1.5hr trip) and after a really interesting tour and chat, Steve replaced them (U1 and U5) I brought them home and kept my fingers crossed that there was no other problems and the board works flawlessly no, so I now have a spare in case I screw up again.
Many thanks to sprintertrd for his help and making me jealous of his huge shed, mill lathe etc etc, he had my mouth watering.
Thanks also to everyone that assisted from the forum.
