[Milsurplus] Germanium to silicon

Good day all,
              I have one of the R-1051 navy receivers
& I am wondering about replacing a lot of the
germanium transistors in the modules with silicon
ones, as the germanium transistors are impossible to
get, especially in the RF amplification stages.
Several of these are leaky. The germanium ones seem to
have lower voltage & current operation than modern
silicon types, 2N700, 2N1224, 2N1225, 2N3127 etc
                Brad
