Am looking for a reasonable cost BCB (MW) superhet tuner or receiver
(valve
or solid state) which has a known sensitivity of 1.0 microvolt or less for
10 dB s+n/n ratio.

1 uV at what impedance? what bandwidth?

Collins R-390A can do that with the unbalanced input with a CW signal,
and exceed it handily.
