  Simon,
  You hit it! I foolishly had two of the Transistors swapped. All is well now.
  Luckily the smoke didn't get out.

  I also noticed the newly fixed monitor is centered better than the old one. Is that adjustment the X.lin./Y.lin. Pot on the deflection board?

  Thanks for your help.

  Bob

    maybe one of transistors is bad I have had a few that were bad from new. Maybe they are in the wrong places PNP were the NPN should be?

      I have been trying to get the 15v2000 in my Ast. Dlx. Cabaret up and running. I have another working unit to swap assemblies from.

      I tried it briefly and got no picture and no glow. I decided to do a cap kit and solder headers and replace chassis transistors.

      Tried it last night and the r100 and r101 resistors got smoking hot. HV was around 25KV.

      So I swapped the suspect hv unit and deflection boards into my working unit. they both work fine in the known good unit.

      So now i have it isolated to the chassis or the tube. The chassis transistors are not shorted to the chassis. I guess i'll try swapping tubes.

      Could it be the harness? The Dag connector spring(I moved it back and forth a bit to break any corrosion)? Can I swap in a 19" Tube to test?

      Any other ideas?

      Thanks,

      Bob
