[Collins] KWS-1 PA current

[Keith Sorensen]

Hello to all,
I am currently bring up a KWS-1 serial 0071.  I have a situation with the initial set up, when going from STBY to CW the PA current will peg and HV fuse will blow with in seconds.  I have done all the initial checks for low voltage supply bias -39 to -96vdc, screen at 350vdc and low VDC running at 300VDC, 25 vdc high.  I have installed new caps as decribed in the "deadly caps" tip.  rebuild the final and dropped in new 7580W, and added the service bulletins. The 2KV supply holds up fine until the "operate/tune switch is in the operate position and moved to CW. I get no screen, ALC, or Bias reading on the panels multimeter  When in the tune position the PA current rises slower but will still peg.  Any tips would be a great help.  I am a new member and this is my first request for help from the pro's at CCA. I really want to put this old beauty on the air.
