Should I buy a board and give it a shot, or am I likely to toast the replacement
board? I would really like to get the data off the drive, although it's not life
or death.

I don't think you will necessarily kill the replacement.
I just think that your chances are slim (read amplifier dead)
and that you may kill the drive heads. There is a chance that
the read amplifier shorts out some power lines and that you
will blow filters on the replacement board. I have no idea
how likely that is though, but you should probably be prepared
tho loose the replacement board too.

In reality you are unlikely to lose the replacement board and even if you do, its not much money to lose.
