 i had the 250w slug not the 500w slug in so in actuality getting about 600w out again, though it is topping out a bit lower with the makeshift traces. I have the matching coil to the other side on order and will swap it in and see if things improve in a few days, but since it is on the bench anyway I'll probably play with it a bit more.

  Back in business, and I found the 300 watts I was missing. Peaked over 1kw on the meter with 25w in.

  I began repairs before PT I actually do have the caps and the wire to wind the coil so I may try it before going thru the trouble of a combiner swap.

That looks a lot like a arc with all that black carbon.

It appears that a coil and capacitor have met their maker and taken some strip line with it. Will at the very least need to repair the output combiner board and replace the coil and capacitor. I might take the output combiner off the spare I have and swap that in since the strip lines are in bad shape. I don't think I have the value of the ATC cap I need for the output so I will have to make an order.
