I understand Ameritron revised the TR relay board a number of years ago. I had an arc over ruin the original and now have a current replacement.

The board has at least seven w (wire holes). The obvious one I can do, coax for input and output, plus DC for relay switching.
However, it appears that is just part of the maze. I believe the sampling circuit for peak power is also piggy backed on same board.
In addition a few other wires of various color emerge from the chassis wiring harness.

The manual of course, is not in anyway detailed enough for me to wire in the new board.

So, does anyone have a photo, schematic or whatever, to aid in replacing the board. The output coax was installed very tight, and now I am thinking it advisable to just take it out and install a new run.

Thanks for any pointers on this rather simple on surface, but complicated in real life technical job.

I posted the wiring of this board to your last request for it. The thread is on June 18, 2011.
I am the last post on the thread and have listed all of the colors of the wires and the hole number they go to. If you cannot find it, I can mail you a copy I have of it from Ameritron.

I hope you don't object if I need further assistant, I use you as my guru.
I am thinking this will be an OK job, now that I have the info and you have saved me time and torment trying to reach Ameriton's tech dpt.
