  Hi Wes -

Sorry to hear about your damage.  Please give us a report when you find 
out what was damaged and if it could be repaired.

I'm using the protection circuit Phil describes in the FAQs 
I think Pete also wrote an article describing a similar circuit in NCJ a 
while back.

I wonder if anyone has ever experienced damage to a QS1R when protected 
by such a device?
