A follow-up on this. I definitely agree on recapping the tantalums - if they are bad or not. It will save you from later having to replace them. Consider it preventive maintenance. Similar to the policy of vintage radio enthusiasts.

But another thing to consider is the head wire socket connections on the sense amp board. Early 67s and the 65 have soldered connections, but later 67s have tinned wires stuck in little vertical sockets. I've seen a couple go intermittent over the years. Bumping the calculator or wiggling the wires will make it work - for a while. Best to rip them out and solder the wires directly to the board.
