Damayante is a nice floor radio with an attractive front panel.

This radio is one of the first Radiomarelli models with tuning dial and can receive two bands, medium and long waves.

In this model, was used an indirect 6,3 V heater new tube series.

Itís a superheterodyne set and is also one of the first radios which works with a multi-grid converter tube, 6A7.

Diagram and chassis of this radio are same to the ones of Damayante model.

The upper left knob operates the power switch / volume control while the right one is for the tuning. The lower left knob (spherical in shape) has two axial positions and is used to remove the sound without switching off the radio. Also the right one spherical knob has two axial positions and operates the switch band, by pulling toward yourself you select the long waves band.

Under the dial you can see a pointer tuning meter which works in series to the anodic circuit of the IF amplifier tube.

Exists a doubt about the muting switch operating of this radio, so I put in the bottom of the page three electrical diagrams which I found in three different books of the age:

In the first diagram there is a mistake and the switch is missing. In the Damayante diagram the switch is located in series to the sound speaker coil. In the third diagram the switch is located in series to the LF signal, between the 75 and 41 tubes.

The published radio, and other two radios that Iíve seen, corresponds at the second diagram, the one of Damayante.
