This model should not exist in reality. It is a hypothetical combination of case and chassis, by misreading of service documentation.
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.
Any other combination is not real.
Unfortunately Beitman ignored the existence of models RC522 & RC527, and allocated all four Chassis numbers to RC521. That is obviously incorrect.
