This model radio employs a three section "candohm" resistor (R10) working as a voltage divider to obtain the negative bias voltages for the 6Q7G and 6F6G tube grids.
The schematics does not gives the ohm values for this "candohm".
I've search over to get these.. but has no success.
I wonder if maybe someone could give a clue with this matter.
attached is a schematics with all the voltages.
Cheers,
Meyer
