I've got a Rotel RB850 amplifier, to which I made some small mods years ago (new Audioquest power cord, real binding posts and RCA jacks). The amp uses dual transformers and rectifiers. I have the schematic, what do the experts think, is this amp a good design or not? Is it worth upgrading some of the parts (I was thinking of input cap, feedback resistor, and 0.22 ohm emitter resistors in the output stage, and perhaps Schottky rectifiers if I can find the proper rating of what is in there now). Or is the design so old that it should be tossed into the basement system?
Thanks,
