Default Building the Akido All in One Noval Rectified for F4s

I have been helping a friend who owns an audio shop build some DIY kits he acquired and included in the kits were an Akido all in one and enough parts to build a couple F4's. I have built one F4 and would like to get two exact copies built to run as monos as opportunities like this don't come every day.

The exact model I have is the All-in-one Noval with rectifier.

A few questions I have are:

- What tube orientation can I use to get the most out of two mono f4s or just one? The kit he has was originally purchased with 12au7s, but i understand they won't give the most gain.

-I will need some help getting the best power transformer. I currently have a 270cax that was supposed to be used with the 12au7s, but I am not sure if it would work with other tubes.

Most kits I have built give me exact instructions and the correct parts for the build, but I since I am changing from 12au7s to higher gain tubes I need a little help and direction.

Do you need gain? Most domestic audio systems do not.
