Okay thanks Andy. Well I would like to mention when I received it, I had about 1.5 watts to the watt meter before starting this original posting.
As mentioned it had the RFX75 installed. After opening the rig up, I had discovered there was a fuse holder inside the rig and this fuse holder went to the RFX75.
When I placed a heavy fuse in the holder of the RFX75 that is when it took out the D8. So it is my belief from what I have experienced, it has something to do with the results of the RFX75.
After doing the mosfet transplant I found out it would still take out D8, realizing there is still a short. One thing that I discovered that I did not have an insulator sleeve around the bolt that that keeps the mosfet in place which could be the cause as well.
After de-installing the mosfet, I have not yet try to place a new diode in D8 to see if this would short again. Also I have not yet removed the driver transistor from the circuit.
I don't mean to derail anything that you are helping me with but I think I have not been to clear with my communications to allow clarification for your wealth of knowledge to lead in a possible fix or at lease to move in that direction.
After rereading and posting I have realized that I had not totally post exactly what I have or have not done, of course not intentionally!
I hope this makes more sense now.
Oh and another thought, when I turn the modulation POT, I do not see any results on the ohm meter.
