I have his "sound of capacitors" in my mental bookmarks. Perfect stuff for showing that some cap differences are quite measurable.

Note the use of a Hammond 1650P in the 3V amp.  :icon_twisted:

Me likes the Hammond transformers too (they must be a canuck), kind of big for a little amp aye hoser? I also think it's rated for push-pull, is that 2N2222 doing the job of the other half?
