Supposedly, John in RI is the expert. However, I cannot get a hold of him. He had health problems in 2020 and 2021, but last fall he said he was back on his website. I tried leaving messages and even a phone message. Nothing. I can't believe there is only one circuit board expert out there, but he's not available and will not share what he does. If you know of anyone that works on these, please share. That is a plea to everyone in the forums
