By all rights it should reduce tube count. The average split sound set had 4 video IF tubes and ~4 audio IF tubes for a total of 8. Contrast that with an intercarrier sound set that had 4 video IF tubes (that doubled as sound IF amps) and one 'sound IF' tube, for a total of 5. That is three tubes saved...Nearly a %10 reduction in a ~40 tube TV.

Perhaps David was in need of coffee, or feeling contrarian when he posted...
