Didn't Harman Kardon make the first stereo receiver back in the 50s? I know they made a tube unit from the late 50s/early 60s.

No one uses tubes anymore. They're obsolete.

Not only that, but they get REAL hot 'n' use WAY too much electricalty.None have been made since the Johnson administration, & nobody wanted 'em even back then. In short, only a 1st-class DORKFISH would have anything that has Tubes in it...

The electrical problem goes away if you crank up several A/C units to balance it out. Being a 2nd-class eegit, I can attest to the fact that it doesn't take a 1st-class dorkfish to use tubes.

Seriously, IIRC, Zenith invented the multiplex stereo system, and the FCC approved it in 1961, so I'd suspect Zenith built the first stereo receivers.

I've seen H/K often cited as producing the first commercially available Hi-Fi integrated stereo receiver in 1958 with the TA-230. The tuner section used AM & FM for "stereo" reception, i.e not FM Multiplex Stereo. This was obviously not the first stereo amp, or first stereo transmission etc., but supposedly the first all-in-one Hi-Fi tuner, pre-amp & power amp.

Forgot about those. But stereo that way must have sounded like crap, getting the phasing right, and also the fact that AM has less bandwidth than FM, and the random nature of how the detector diodes are wired (my Fisher 500 has a polarity flip switch for the AM detector). And the noise that AM doesn't reject, but FM has different kinds of noise. It would be like using two mismatched speakers (one Bose and one JBL?), or using two mismatched monoblocks.
