I haven't seen photos of the new ST70 board installed so I thought I'd post a few if I can remember how to do it.
Since the board is the exact size of the original it went in easy and was easy to connect since the connections are marked the same as the original, it took about 40 minutes total to remove the old and install the new, probably an hour for a beginner. Of course it worked perfectly on power-up, and I didn't even have to change the bias settings as they were still correct.
