The horizontal output tube failure can be caused by a non functioning horizontal osc. This will cause the severe over heating of the hot from not having any grid drive. The plate will turn RED and get so hot that it cracks the glass where the wire exits for the plate cap. Tube goes to air. It doesn't make the flyback too happy either, can cause it to fail or to short some turns.

Vol 1-50 admiring the old set and trying to
