[Elecraft] K3 assembly issue

[John Oppenheimer]

Hi Adrian, welcome to the hobby and to the Elecraft list,

Wow, that's quite a collector's item! I'd consider asking Elecraft what
they'd charge to assemble and align for you.

This unit has never been powered up so I suspect it has to be a bad regulator. I can solder a board just fine and assemble PCB’s but I’m not overly comfortable with hardware debugging. I’ve removed the side cover and checked for loose boards, bad connections, etc. with no success. Anyone have any ideas how I should proceed? Do I just replace the regulator? Do some other debugging?
