All this talk about trees, how are you implementing three phase?!?

Hi!There is an article in Sound Practices 17. This issue was only released on the archive CD.
There is nothing special about it. Three phase schemes can be found in many electronics books. For example in the first chapters of the RCA transmitting tube manuals.
There's also an article in wikipedia. This is the scheme I typically use:

only TV dampers instead of the silicon diodes.
Let me know if you have specific questions.
Thansk Thomas. I understand the use of 3-phase and its advantages but are you using direct 3-phase service in the home or synthesizing it from single phase?

Hi!3 phase service right out of the fuse box available over here :-)
I remember discussing the 3-phase supplies with you quite some time ago. Short of running a rotary converter it isn't an option for me. But I might have a chance to pick up a bunch of SLA batteries from a UPS that is being replaced. That would give me a 480VDC supply (but I am a little concerned about safety!).So have you ever tried a battery (only) supply for B+ and if so, how did it compare?
Hi!No I haven't. I plan to run a phonostage off batteries. But that's a future project. A friend of mine is using a battery powered phonostage and likes it very much (he uses 3 phase for most of his system tto)
just to see what happens. I'll post the results when I'm done.
