FOR PARTS, NOT WORKING, UNIT DOES NOT POWER ON. This unit was given to me by an associate. He knows I have a unit already, but said it does not come on. He said he no longer wanted it. I dont know what is wrong. I am not a tech. It is not cost effective for me to send out for service, plus too heavy for me to maneuver around. So I am selling it as is. Local pick up is preferred. I know that the one I have is an excellent performer. I know the listed price is very low, but, it is an opportunity for someone to have high end equipment. or a service center to have great parts for service
