[Milsurplus] G11 Dioede

[Peter Gottlieb]

You will have to experiment.  I don't know the circuit or how critical the 
voltage or voltage matching needs to be.  You might also try other more common 
germanium diodes that are still available or Schottky diodes which have a 
significantly lower forward voltage than regular silicon diodes.
