I have been very careful and very slow. The Cornet2 is my first project. I am following all instructions and doing no modifications, except as recommended by Hagtech, i.e. the upgraded capacitors. The circuit board is completed. Now I need to do some testing. The DMM should be here tomorrow. Never used one. I don't have an oscilliscope. I am just going to check the voltages and all the connections I can. I hope this is sufficient. Should have a report by the weekend. Thanks for all replies. Do you have a Cornet2? What do you think of it? Larry
