Thanks Opacheco: This is what I am looking for: What are YOUR results.
In addition to the user experiences (which are obviously the most worthwhile), do note that most tube databooks have info about (actually warnings against) significantly different heater voltages. Also lower is not pretty, at least from a technical point of view. A Philips databook sez: influence on both performance & lifetime. Keep deviation below + & - 15% (design max. value).Bye, Peter
