Apparently the board was 100% operational so I guess I could have fried the VCA desoldering it from the board. Still doesn't get me closer to working out what the problem with the CS80 was. A good result however.

Hi Nigel - welcome to the group.  Good news it's working now.  I didn't have a chance to look into this before you fixed it.

FYI to any other group members trying to get hold of me:  I've been very overwhelmed recently with both work and a very sick family member so lot's of stuff around the house, including CS80 work, is being neglected.   I'll be catching up soon (I hope) on this stuff.
