Notes
The Zenith Stratosphere 100-Z was introduced in December 1934 for the wholesale market. Like the Scott line of deluxe consoles the Zenith Stratosphere 1000Z used also a chrome-plated chassis. The 100Z has 5 bands covering 535 to 63600kc but the 63600 kc were soon dropped to 45000 and later to 32000 kc. The Stratosphere 1000-Z comes with 3 speakers; has two subchassis: lower 2501P power supply, upper 2501C control (receiver). It was designed in 1933 and 1934. There are several interesting books about Zenith and some articles about the Stratosphere 1000-Z. It was a milestone for the radio industry of that time.
