Unit is in nice condition! Indicator light turns on and the tubes heat up. Unit isn’t further tested.. I couldn’t find much information on femco but I do know they made old coal mining equipment as-well. Item is in overall good condition, item may show a few signs of cosmetic wear/flaws due to storage/use. Please view and inspect each photo before purchasing. Once receiving feedback, I’ll post a positive for you also. I ALWAYS try and work with everyone to make sure you have a pleasant experience with my sales. Cost Will Be Additional For AK, HI, PR, VI & GU.
