Default Re: F. Stephen Masek's HMV468 restoration

It is finally on my work table. The schematics I have show a resistor in series with the field coil, but this radio was built with another choke in series with the field coil. It is original, as it supports the terminal board for the cable to the speaker.

The two large Bakelite blocks for resistors and capacitors under the chassis are also different that what is shown for the Marconi models.

It would be nice to have a schematic for this radio, but I will probably have to draw it by modifying the Marconi schematic.

The choke and terminal board (I untied the wires to trace the circuits)

The main power fuse, an unusual (to me) yellow thing
