I have a radio from MF without model or any other indication It is imposible to fix without the schematic. The date of manufacture may be something between 1935 to 1940. The tubes are: 25Z5, 78; 77; 6A7 and 43. The main trouble is in the power supply distribution, that seems to be very sophisticate. The result is that in the control grid of 78; 77 and 6A7 the bias is near minus 27 volts.

Can anyone give me some help??

Please answers in Spanish English or French  

Francisco

Hello Francisco,
Hello Everybody,

Could you put some photos on your thread to help to identify ?
Of course, an other way is to take down manually the schematics... Often a hard job !

Maybe "242" model (1934), LW/MW, IF = 135 kHz, same tubes :

If it is the model you search, let me suggest you to put your questions from the model page using Add information or ask a question link (also on the model page).

Regards.
Jean-Pierre

Hello everybody,

I got an answer from Francisco :
- his radio is a 242 from Manufrance,
- he had some PC problems (will be fixed in few days),
- he'll write some infos from the 242 model page asap.

Regards.
