How to repair modify Johnson Valiant Ham Transmitter PTT circuit

Very involved repair underway of a vintage Johnson Valiant. Numerous problems which I will feature here on Youtube. The Valiant as well as all Johnson transmitters are very well built. True classics back in the day and now. I grew up with them. Have a few in my station setup. Always team up with National receivers. If you have a EF Johnson in need, watch the videos I have posted. Or if you would like me to repair it, bring the boat anchor to D-lab!
