Hello Big Boat
I am a first time person to this forum. I congratulate you and your parteners in this project. It is nice to see someone share the knowledge they have gained over the years with other people. Well Done.
I have built the small rc board and had it working for one hour ok. I also built the first board design with problem in the timming circuit.
I used the small board to check voltages and it to stopped. Both boards are ok on the high voltage. The problem is the trigger voltage from the pic output pin six. Im only getting .07 volts out max ,the thyristor needs aprox 5volt on the gate. It is the same for both boards. Can you Help with this problem and what would limit the output from the pic.

best regards to all
