Well I did it now <GRIN> forgot to turn the antenna switch to the radio I was testing and my output dropped to about 1 watt, brought it back to the bench, No output and it blows the 3 amp fuse when I transmit.
Tried transmit with 12 volt supply did not blow fuse but no transmit,
Step-down transformer started making a intermittent humming noise, connected it to the scope voltage steady but weird wave form. see image
I assume I blew the final and maybe took out the transformer or possible cap??
Need some help to know were to go from here?? No Schematic
Thanks Plumber-G
