The KSTP-AM aircheck sounds fairly “bright” but high fidelity ?. The “hum” when the microphone was on pretty much ruins that claim for me. Here is an ad showing the “high fidelity” 1957 Webcor “Musicale Coronet” that they advertised in the aircheck. It is the small player, bottom right in the ad… high fidelity?
Anybody guess what year ‘vette is shown at the top of that page?
