An update --
I just replaced the 1k R14 resistor and the voltages around Q4 were still the same. But I hadn't actually tried the board with my turntable so I thought I'd do that before looking for another problem.
And, yeah, it works. I'm still not sure if I should be concerned about the voltages around Q4 or not, but it does seem to be working now. I'll case it back up over the weekend and hopefully get back to some Pearl goodness.
Thanks for all the help everyone. Maybe someday I'll be able to help you guys out in return.

Around Q4
16.4 (14)
17.3 (19.3)
16.4 (13.4)
Maybe your readings are not perfectly correct. You can't have 16.4 in both positions as the base of Q4 between these points takes about 0.5V.
Have fun, Hannes

It's possible. My skills are questionable and it might be time for an meter upgrade too.
