Replacing Germaniums with Silicons on my old Soviet radios

[bigtom]

HI
    Just to say that I have one of  V F 206  Russian radios . I came into my possession in bits although there were no missing parts. It works really well. I use  six rechargable batteries to work it.I could never find  a proper  replacement  for the Dial lamps.They  only draw  60ma  current at 2.5 volts.Is there anybody out there  who might know  a source   for them  or something similar.
    
Thanks
