Had you mentioned this in the beginning, surely the conversation would have been of a different flavor. When I, and I expect others as well, read a posting, we respond at the apparent level of the OP. That is not meant as a sign of disrespect (which you seem to imply with your posting of ability), but is to be able to communicate at whatever level of experience the OP appears to have. Those of us with serious electronics backgrounds do not want to make a less knowledgeable person feel bad.
Yes, my posting (one of the “last few replies”) may have been irreverent to you, but maybe not to others reading this thread when looking for help.
I have no machines like yours, but I enjoy reading about them. You never know where a solution to your own problem might come from.
