The Grande idea follows what Fisher, Scott, and Sherwood did. Small signal circuitry that works with "12" W. tubes also works with 7591s. ;>) Those folks were both good HIFI people and smart businessmen. :>D The Scott 299A, 299B, 299C, and 299D pretty well show how it's done.
Use the original "El Cheapo" schematic and increase the B+ rail voltage.
In another "leg" of this thread, I went into some detail.
"Hit" Frank Philipse site and download the TungSol 7591 data sheet. Pay close attention to the conditions given for a UL mode AB1 PP O/P pair.
