diodes

I have the Sansei Hi-Fi 6 tube 2 diode radio
the diodes are bad and there is no replacement part for it.
can someone draw out the diode circuit for me and or suggest a replacement alternative.
it seems no one has found the schematic for this yet.

thanks..

Japanese Radios are very difficult to find information for.
you would need to supply the model# to have even a chance at getting help to say the least.
