Dave,

I think they should go at right angles to each other shouldnt they? To minimise induction. Obviously, with 4 transformers in a confined space, this will be more of a challenge. As long as you keep the mains trannies away from the output ones, i would think you'll be ok. I recently built a single ended stereo amp using a couple of ECL86's. This used a single, torroidal, mains transformer and the two output trannies. I had a slight problem with induced hum into the input of one channel, but i cured it with a small piece of aluminium for a shield.

Good luck!

Best regards
