But no IF amplifier stage. It's a very interesting minimalist superhet with the mixer stage called the "oscillating translator", with IF being 175 khz.

Colonial Radio always referred to the convertor as a "translator".
It's a late addition to Rider's VI. It's more like an early 30's entry!
They used the early 6 volt car radio tubes. Anything to get around RCA patents.

Wasn't the car battery the reason for tube heater voltage finally being standardized to 6.3V ?
