Description
The Carmen 4 S 691 A is a tube radio receiver for export, made by Electronica in Bucharest [1]. It is built on a printed circuit, has separate coarse and fine tuning and tone control, and a modern-looking cabinet of mirror-veneered plywood [1]. The Aida has an identical circuit [1]. Its circuit is different from that of the earlier Carmen 1 to Carmen 3 [1].
In the source table, sensitivity is given on medium waves for 0.5 W output, selectivity for a signal ±9 kHz (AM) or ±300 kHz (FM) away, the audio response within 6 dB, and output power at no more than 10% distortion [1].
