"The S-5000 will actually drive MMGs if you restore them properly..The biggest gain in the S-5000 is unquestionably a 35uf film cap and the improved ground scheme..Just that alone with a basic 2.5 time increase in capacitance really makes the amp's stability improve a lot."
I suppose it's all a matter of taste. Being a bassist, I really don't like bass shy arrangements, and MMGs with an S-5000 just didn't have the dynamic headroom that I prefer. Of course this is a matter of taste, source material, etc...
Maybe this thread isn't the place, but I'd really like to hear more about your power supply mods on this amp. I too have noticed that the ground situation is a little odd on this amp; the bias supply has a floating ground on some versions, while on the earlier versions, the transformer had a center-tap on the bias winding. Where in the HV+ supply did you place the extra 35uf? I assume at the stage following the first current limit resistor?
Cheers!
