My Empeg MkII (Hijaak kernel, one of the latest versions but i don't remember the point) has a problem with powering up on A/C power. It works fine in the car. A friend of mine with a surface-mount repair bench is working on it for me, but neither he nor i is an Empeg expert.

He has gone through these threads and has CHECKED the connector switching problem (not the cause) that's on the FAQ as causing this problem. He's nervous about futzing with any more hardware without at least a better indication of where on the board the problem is likely to be.

There was a blown diode on the board when i turned it over to him, but he has fixed that and there is no change in its power status.

If you have a clue what would be causing this, and have shareable schematic pieces or other detailed information, post here, or reach me at (adrienne) DOT (travis) AT g m a i l (dot) c o m.

Thanks!
