Just for fun, I brought one of my 92101's (with a 6M plug-in) to the 
1996 Central States VHF Society Conference and entered it into their 
Noise Figure measurements.  Albeit, mine wasn't the worst it's hard to 
beat modern GASFET amplifiers, hi.  My guess is the two after mine also 
had serious problems.

50 MHz    Call    Design    Device    Input Network    NF (dB)    Gain (dB)
             K0GJX    ARR    GASFET .65         24.48
             K0GJX    ARR    FET     1           16.48
             KB0PE    OWN    RCA 40841    TAPPED L 3.26       14
             N9OO    MILLEN  92101 w/6AK5    LC 7.3        13
             N0AKC    DEM    ATF                                 
7.9        6.4
             KE9QT    ARRL HDBK    MRF966 15.4       7.9


If anything it was a conversation piece at the event.
