ASR 33 buzzing

So I've got the machine being quiet now (no buzz).  And I've confirmed the unit does not try to engage the motor unless switched to Line or Local mode.  The second you turn the switch, the motor does about a 1/4 turn and then there's a visible spark from the bottom of the fuse holder.  So I'm guessing this must be caps or something drawing too much power somewhere.
