Default Replacement power transistors hfe.

I am looking for replacement power transistors for my heathkit ip-20 power supply, replacements that are in my budget have a lower hfe than the originals or their equivalents. The originals/equivalents have hfe of 100 min and the replacements that I have looked at are 20 hfe min.
Will the lower gain transistors have any adverse effects or require modifications(which I don't want to do)? They are to3 packaged Ge pnp types.
regards poppydog
