I found this schematic of a tube/valve ratio detector at http://www.r-type.org/addtext/add059.htm. Does this circuit work during only one-half of the IF cycle. What are the current paths above and below resonance? It's an intriguing circuit and I seem to be missing one thing to make it click.
Thanks all for any help.

An overview from a math perspective. Usually omitted because radiomen and hams aren't expected to know this much math.
