Thanks Mondial.  I've already restuffed the input caps as well as all the rest and installed them so I think I will install that cap and hope the hum is not too bad.  If it is, I can always restuff the input caps or just tuck the 10uf polys underneath and only be out a couple new 8uf Ecaps.  No great loss.
  I appreciate your explanation of how and why that cap was added.  I learn things every day on these forums and love it.
Thanks again

Dick
