I picked this up at the auction a couple days ago, just got a chance to pull it out of case.. Its a japanese made tune amp, thinking from the 50's from the brand "General". Wasnt working so I replaced a couple 40 ohm resistors from the recifier and fired right up.. The Interesting part is that it had Dual tuners for the left and right channel, have no idea why and have never seen one like this.. My brain doesnt work good enough to listen to two sources at once, but oh well.. another one for the shelf :) oh yeah, Ten Bucks..

    I think you are asking the wrong question in regards to the tuner, the real question is "Why not?" lol

    Seems like a lot of engineering for something that no one would ever use, at least no one I know, lol

    During the 50s and early 60s there were stereo simulcasts that used two stations, sometimes one AM, the other FM.

    Exactly so. One channel AM, the other on FM. Pre FCC acceptance of compatible MPX (ca. 1961).
    Interestingly, my father was broadcast engineer (or so he always told me) for the first AM-FM stereo simulcast in Baltmore (ca. 1957).

    Really cool, I've never heard of the simulcasts before.

    The AM tuners in the "AM-FM stereo" simulcast tuners were as good as AM got in terms of bandwidth and flatness of frequency response.

    The HH Scott 330 is a good example, e.g.

    My old man would've been at WITH at the time...
    Here he is recording a remote on an Ampex 600 at City Hall, again, ca. 1957

    The guy with the microphone is Nancy Pelosi's father... who happened to be mayor of Baltimore at the time :-)

    Don't forget the mighty Fisher 800.

    Whoa; howdy, and happy birthday, if memory serves, Russ!

    That'd be the unsuffixed 800... wouldn't mind having one of those myself...
