Ok, so if someone can check my "understanding" on this.
After reading, and studying the srpp circuit, it is in fact, only simple on the surface. It is, in reality, an interwoven balancing act, where one modification in component "value" affects all other "values". It also must be designed around a specific load, as the load is in fact part of the circuit, and thereby a component "value" in itself.
The 6SL7 doesn't really lend itself to this particular application due to it's high amplification factor/mu. As a drop in, it can sound nice with a signal of low voltage swings. But add in a more dynamic signal, and those voltage swings can become extreme, and not particularly "linear" in actual application. The 12xx7's would also fall into this category?
While the 6SL7, could be designed to work, other tubes are more suitable for an output stage, (probably why it's not often seen in this application?). But by it's nature, the srpp can also give substantially variable results, due to it's load sensitivity.
Would this be at least partially correct?
