Default vr tube replacement

I want to replace the vr 0A3 tube used in the bias circuit of a 6146B

the diodes or will I need to make other modifications to the circuit?

If you use diodes rated at the same current as the 0A3 (40ma) then it
should be a direct replacement, at least for a voltage regulator
application.
