      That.s good infos.Thanks. Oh ,yeah , it is a note in generic 200w Major schematic you posted.Bias CT is Yellow wire. In this case lift just yellow wire and run it directly to bias board. But always better to check first
      There are allready some errors like blue-yelow-blue for bias winding. There are pink as I saw
      The green wire is indicated as be heater CT or electrostatic shield. Let it in place
