Has anyone build the Pine board project. I want to build it. I only have one question. I am not sure where and how to connect the key. I only want to run CW. Don' need the preamp at this time. Other circuits I've seen connect the key to the cathode and other side to ground, sometimes thru a coil. Is this correct? Am I going to have high voltage on the key? I don't think so but want to be sure.
Thanks TOM N8CHR
