Well... this might be tricky then, as I've already gone through the service manual and looked at the voltages, and they changed accordingly to sp, lp, and slp, no matter where I have the switch. For example, pin 10 of the speed "auto select" IC is 0v when it's spinning fast, (sp) then 10v when it spins slow again (lp or slp) Another curiosity is that pin 12 on that IC shows 6v, which should mean that it's in record sp mode, but pin 13 shows 0v, as if it were in play mode. Pin 13 goes straight to a "record 12v control" transistor, so it looks like the speed control IC is in record mode even though that transistor isn't telling it to be.
