- Notes
- The SE-AR-DE Radio Frequency Amplifier is designed to meet the demand for a unit which can be used in conjunction with most any type of set, especially those in which the tuning unit is separate from the detector.
This set is fitted with Acme transformers and has an anti capacity switch which allows the operator to cut out the radio frequency amplification and connect the tuning directly to the detector. This unit sold in 1923 as Knock down kit for $28.00, assembled less cabinet for $35.00, and complete with cabinet $42.00.
