This arrived today. Decided to take a punt since I will eventually need one for faulty MK2 PCB.

This was the EBay stock photo:

First up clean the board and re-populate it. Added all ROMs, the missing PLCC at U1 and the U7 chip. Also changed out all the electrolytic radial capacitors, the axial caps are usually ok to remain.

Fitted the missing amp and added missing heat sink

All neat at the back

Straightened out the bent parallel header pins

And the power header pins - these were properly bent over (hard to tell from the Ebay photo).

Light on and it's fully working - wish they were all like this but they're not.
