• Notes

• A folder from 1927 reads: "Like the RFL90 this five-tube RFL75 radio incorporates the famous non-oscillating and non-radiating RFL circuit. Perfect balancing is achieved by introducing the Wheatsone bridge into each stage of amplification. ... A genuine Crosley Musicone is built in and plenty of space is provided for batteries or power equipment. ... Conole is mahogany." The price for the RFL90 has risen to $ 98. From Crosley folder for resellers, 1927.
