Think I smoked something?

204.56.36.138

OK, I know "take your time and do one mod at a time" BUT...
I upgraded some caps and resistors in my 6L6 push-pull monoblock amp (at least I stuck with modifying one amp at a time). Unfortunately, my schematic has some readability issues. Thought I was replacing R10 with the specified resistor, but the spec I was reading was for R16. Should've used a 56K ohm 12 watt in R10, but I inserted a 100 ohm 1/2 watt. I also should've alerted to the fact that the resistor coming out didn't match the spec, but the drawing didn't reflect the labeling on the PC board for one of the coupling caps either, so I was just convinced the drawing was wrong (pretty stupid huh?). Anyway, fired it up and nothing smoked, but of course the sound was terrible. Since Auricaps sometimes take some break-in, and I switched caps at the same time, I left it on while I pondered what could be so wrong. After about 25 minutes, I discovered that the spec was showing two R10 values. That's when I figured out that I had inserted an R16 value into an R10 spot. Now I have changed it back out and there is no improvement in the musical quality. Nothing on the board looks to have gotten too hot. Any recommendations on just what might have been damaged downstream and how badly? Tubes won't bias correctly, switched to some dubious back-ups and they won't bias either.
Link to schematic attached.
Oh, I changed the coupling caps from 0.22uF 600v to 0.47uF 450V. If nothing smoked, could this cap change really be smearing the music this badly? Spec calls for 0.22uF 400V
Thanks!
