Needs fixin'

I picked up this old ring flash for nothing, so it doesn't owe me anything . However I tried it on my camera and it worked a couple of times then died . I took it to the camera club to see if anyone could tell me what had gone wrong . Imagine my horror when one of the guys said - have you tried your camera since, it might have 'fried' it as the voltages are different' !! Thankfully the camera is fine - although for a split second I thought 'what camera would I buy with the insurance money ' !
