My personal experience was that 550mV was the point at which my F6 started to sound good. Below that, it just did not sound "right". Above 575mV I could not hear any improvement. More bias just increased the heat sink temps.
Thanks for the words of advice. And the giggle. I needed the giggle. Speaking of giggles, for giggles, I tried the amp this morning, to see if the bias would still hold. R7 (the zener feeder) is smoking. I tried the 3k ones with the 6V8 zener that Zen Mod suggested. Looks like I did something wrong. Luckily I have the stock kit resistors and zeners to try as opposed to waiting for another Mouser/DigiKey shipment. Regardless, time to trouble shoot before I fry another resistor or two. Before that, fresh air and sunshine!
