Re: KB WV20 Warwick
Have you replaced the (I think 0.22uF @ 250Vdc working) capacitor that couples the video from the PCL84 pentode section's anode to the CRT cathode? If it has been left out, it could well cause poor LF response on both line standards.
In production, they usually fitted either a TCC (Supamold or Duomold) yellow plastic cased or Hunts red dipped, resin cased type, with axial leads.
