Thank you all for chiming in.
Picked up the lemon ammonia on the way to the lab and was ready to rock and shock the crap off some test boards.
Popped open the "New" CP2600HT shipping box and it was not new
The packing job was mostly a brown box around the whole unit. Dents and a broken hand
And first start with a full tank of tap water nada no shake, turn on the heat and have bake but smoke also
Nice smell of burnt cap or somthing.
I can peek in the bottom vents and see the transducers are still on the tank but cant see others. now i hold on shipping it back to the seller or idk what will happen.. Fing ebay
