Rear view of the receiver when removed
from its wood cabinet. (Very heavy!!) This is a "great class" receiver
due to its sensibility and selectivity. The schematic is a classic
superetherodyne but with some interesting technical choices as described
in the next pictures. |
As you can see here on the right picture
the final power BF stage is in pure "A" class with a pair of tethrodes
6V6. With this configuration the output power is 10w about, a great
power to drive the big loudspeaker mounted in this receiver. |

Here you can see the plug for the EXTERNAL
MF stage. In this receiver infact the AM and MF stages are separated.
Unfortunatly my receiver doesn't have the external stage... On the
tuning scale there is the Modulation Frequency decals and the variable
AM capacitor is with two cams, this to drive the other section. |
Front view ot the receviver. You can
see the magic eye (on the left) and the big and easy redeable tuning
scale. There are four little lamps in order to light it. |

Here you can see the only BAD component
I had replaced. It is a classic 16MF 500Vl capacitor for the anodic
supply. After its replacement the receiver worked fine. |
Detailed view of the AF stage. You
can see the ground shield on the bottom of the picture. All the
AF stage infatc is perfectly separated from the rest of the receiver,
this to improve the signal to noise rejection. |

Bottom view of this Allocchio Bacchini.
Note the big wheel in the center on the tuning knob. With this wheel
the tuning searching is more "fluid". All the components in this
receiver are mounted perfectly, and in this picture you can see
the ground wire absolutely right angled to the rest of the chassis. |
