I'm looking for a balanced pre amp and would like tp make myself if there is a complete kit available. I've found some but not much helpful info on google. Is/has anyone done this sort of project, could point me in the right direction. cheers

I wanted to know this as well. I was thinking along the lines of a tube pre amp. There are a few designs out there but the kits seem too expensive.

I have built a preamp based on the design of the K&K (I used Cinemag input transformers, magnequest output transformers, and a quad of 12A4 tubes, and a different CCS, and a different PS, but basically the same idea.) It is a nice design, though a lot of work for 8db of gain (mine is more like 6db.) I am tearing it apart to use the parts elsewhere and build something similar to the DIYHS, using their TVC's. I can't give an impression yet on the second one. Both of these can take balanced or single ended and can output both balanced and single ended signals.

There was the Pass Aleph P1.7 clone (supported by Nelson Pass) on DIYAudio (diyAudio Forums - (one more) ALEPH P 1.7 clone_. Not a kit, but you can buy all the FETs matched; after that it is just some caps and resistors, etc. to source. And chassis, I/O, volume control

The M3 can be made into a balanced preamp.
