Hi All, I have two Tic ring rotors that are surplus to my needs. Both are for 45G/55G tower. I hooked them up to the control boxes and both worked fine. Price is $600 each. These things are very heavy so they are pick-up only in the Coos Bay, OR area or I can meet you in Roseburg near I-5 to deliver them. Please reply off the list. 73, Larry K7MI
