I was out with the horses tending to one with a summer sore - unfortunately no nurse to help. I arrived home after midnight and the wife was using my computer so I watched a bit of TV - don't do that often anymore. Looks like some good numbers for a maximum output after rule number one was applied.

Did you test this at more than one frequency?
It will be interesting to see how the frequency response improves at the low end with the upgrades.
This is a beautiful specimen of a 700B - with the mods this will be a kick ass amp.
