I recently had to replace a few transistors. I came up with the following list of transistor equivalents for those listed on the Neumann schematics.
VMS Part# = Equivalent Part#
-------------------------------
BC107 = BC237B
2N4036 = 2N4036 (end of life)
BSY90 = 2N2219A
2N1613 = 2N1613 (end of life)
2N3055 = 2N3055
BD109 = 2N5192
BC107B = BC547B
Feel free to chime in with corrections or other part equivalents. We should have a resource like that here.
