Dear Francis,

the Becker Solitude 3 needs a low impedance speaker.

The schematic shows a tapped output transformer, the lower secondary winding requires 2.5 Ohms as a correct speaker load. This connection ends at the screw terminals. You may use two speakers (each 4...5 Ohms) in parallel to ensure proper working.

If only one loudspeaker (4...5 Ohms) is used, the speaker connection at the output transformer should be changed from the center tap to the (unused) high tap.
