I just bought a couple of 5680A's that have the same FEI p/n. They are pop-riveted to a heavy double-sided board., obviously cut off from a longer board. I've removed one of these from it's board/heatsink. There are two pots on the board, only one of them can be trimmed with the case on. The sinewave forming filter and maybe countdown chips are not there, and never were. There are three identical voltage regulators on the heatsink spine. I'll be doing some more reverse engineering on these units; they were so cheap I had to have a couple! If only FEI was more helpful! hey must have moved on from these, and could put one manual out there? Oh Well! Don
