Not knowing what the preference is and given a smaller budget you could try for an OP-amp based pre:

This is the Mini-Pre as sold by Schuro at:

I think there are 3 different budget levels at Schuro and I suppose you could fit some version within yours using different parts or already existing stuff.

That is an OP-amp based pre. Some people think that is OK and some not.

For a discrete design I am sure you would also be able to build a BOZ on a tight budget. I find this approach more appealing. Try:
