19.2 volts out of PS, 18.5-19.2 on the mobo pin I had just resoldered. 
When I pulled the unit off line it was because it had just 'died' for 
unknown reasons. So I'll be dismantling it again, hopefully find the 
cause somewhere along the line. Right off the bat I pulled the speaker 
connector right out of the mobo as the the connector halves just 
wouldn't undo. Could've been worse, the speakers I don't need anyway.
