- Annotazioni
- The Aztec cathedral is a tuned radio frequency (TRF) radio that uses the following tubes: two Type 245s as push-pull, AF power tubes; three Type 224s as 1st, 2nd, and 3rd RFs; a Type 80 rectifier; and a Type 224 detector. A promotional ad to entice dealers to sell the Aztec says, "Dollar for dollar, you will find it hard to beat the Aztec for value. It is the outstanding offer of the day... Gives a real 7-tube "AC" radio complete with tubes and Magnavox Dynamic Speaker at a price that is less than many inferior models... Read the many points of merit and you will see why the Aztec is selling like hot cakes in every locality."
The twelve "Points of Merit" are as follows: Genuine Walnut Gothic Design Cabinet Magnavox Lifetime Dynamic Speaker Push-Pull Amplification with 245 Power Tubes Three Stages of Tuned Radio Frequency Screen Grid Tube as Detector Balanced Radio Frequency Coils Sturdy Construction Shielded Steel Chassis Single Dial Control Kilocycle Dial for Accurate Tuning Efficient Sensitivity Tuning Illuminated Dial for Easy Tuning New Tone Control and a Phonograph Pickup Jack
