This is an overview page for the different RR30 models and also pool for the available technical documentation.
Models can be discerned by exterior appearance:
- RR brand
- with cloth
- with a magic eye frame that has stripes left and right (early model, not yet in radiomuseum)
- normal magic eye frame (model with EBF80, with EF89)
- with plastic grille
- with cloth
- Ei brand
- with plastic grille
- pastic grille with wide frame, covering most of the front, flat (model with 2x ECH81)
- with plastic grille
- Barclay
- same as Ei
There are also different schematics and technical differences:
- RR230, with EBF80
- the schematic lists rectifier EZ21 as alternative (included here but not interchangeable with EZ80)
- we don't currently know of any models equipped with this special recitifier type (it was likely only made in Yugoslavia)
- RR230-a, with EBF80
- the suffix "-a" might have been assigned to the previous version when "-b" was released, there are bascially no differences (see note below)
- RR230-b, with EF89
- detection with diode AA103
- the combined schematic "-a" and "-b" shows an output stage with negative feedback (not present in the first schematic). We cannot be certain that this detail applies to "-a" as well, as the drawing mostly represents "-b"
- RR230, with two ECH81
- this might be version "-c" but no schematic is available as of now
- this set probably uses diode AA112
- the schematic might be the same as chassis RR430
