Tesla 621A Opera

The radio has a fine tuning on short wave, switchable band width, magic eye tube, tone registers and control, push-pull amplifier with 5 W output power and a speaker with 27 cm diameter. The cabinet was made in two versions, either with flat or round top panel. A similar radio was the 616A "Indian" which had decorative wooden bars placed in front of the speaker, reminding of a pipe organ or Indian's headband.
