Had same experience, John. SE PA had an active dealer who sold a bunch in the 1970's.... I had the impression their RC oscillators doomed them. The S Sovereigns were supposed to be budget line, but Taylor Music was selling 10 generator Sovereigns for around $30K installed then, which seemed a lot of money when you looked at the guts of the organ. Maybe the "sewer pipe" speakers were gold-plated inside...?
