• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

The way they are laid out on the website: k-12 needs a big space between mains and OP tx's.
By just turning the mains tx by 90 deg, you will be able to place them much closer; probably within an inch of each other without danger of interaction.
To be more specific, the windings of the mains tx should be at 90 deg to the windings of the op tx's.

Ya, this is my first go at an amp. I'm learning as I'm going... it's a slow process, but I'm chatching on little by little. I built up the amp stock on the breadboard, now I'm moddding it and putting it in an enclosure. I've attached a picture so you can get an idea of what I'm doing. The power trannie will be mounted underneath, but I'll leave the output trannies on top. The sheet is 8x12. You could probably go smaller, but with the tighter space you need optimal planning and layout (I have little of both).

Maybe this will work.
