| Notes | The RCA 2C521 is an AC operated 5 tube AM clock Radio. AM tuning range: 540-1600kHz. Has appliance outlet on rear which may be controlled from clock mechanism. Color=Maroon. There are three case variations: Model 2C521 is maroon, 2C522 is ivory, and 2C527 is of white color. There are two basic chassis: RC 1120(-1) for the maroon set, and RC1120-A for the ivory and white sets. By obviously technical reason the tube locations of the Demodulator/1st af and the output tube had been interchanged. The 50C5 was moved towards the speaker, and the 12AV6 closer to the IF-transformer L4. The revised chasses received new designations: RC1120 became RC1120-B, and RC1120-A became RC1120-C. That results in six different Model/Chassis combinations. Six more combinations could be derived theoretically by misinterpretation of service documentation. We list them with appropriate warning remark to avoid future errors. the real models are: - 2C521 Ch= 1120-1 (with or without suffix), - 2C521 Ch= 1120-B, - 2C522 Ch= 1120-A, - 2C522 Ch= 1120-C, - 2C527 Ch= 1120-A, - 2C527 Ch= 1120-C. The particular features of chassis 1120-D are not (yet) known. |
