    Hi,
    Well actually the buzz is in the monitoring receiver when the 3825 crystal is selected in phone or cw. In vfo mode it is fine. I do get a buzzing response from the key in cw. I get only a buzzing carrier in am but no modulation.

    First of all, try the crystal in the other position. Then, try another crystal.

    Next, clean the VFO / crystal switch followed by replacing the 6CL6 (V-3) crystal oscillator / buffer tube.

    After that, you are going to have to do some actual troubleshooting.

    Fine business Glen;
    I did add a jumper between 11 and 12 to the forward wafer of the tune stand by switch to fire up the second 6cl6 in the tune position according to the manual.
    I just wasnt hearing my self in the reciever. Maybe that up set things some how it
    was working before. I might need to add a cap to ground.
