[Elecraft] K3 overheating smell after an hour or so.

[peterc281]

I know this is like asking how long is a piece of string but like they say,
if you don't ask  
I recently replaced the volume control in my rig and since then if the rig
has been running for an hour or so I notice the smell of an over-heated
component when I come into the room.
The front of the right hand side panel near U12 5V regulator seems warmer to
the touch than I would expect but everything is working fine.
I have done a careful visual inspection and found nothing.
It is a 100W rig with ATU and SubRcvr fitted and the input current with
13.5V is 1.54A which seems a bit high.
So the question... anybody got any ideas where I should look?
