how many folks have +10kVA trannys before the rig?

I thought I might have seen one posted in the "all out assault" page here once...It seems like a good idea to me. I wish I had the means...

I've got a 5KVA GE step-down wired for balanced AC output (derate by half) feeding two amps of 500W draw each. The idea is to isolate, so a single household one defeats some of the purpose, but not entirely. 10KVA, single phase transformers are rare and about 200lbs. Most that size are 3-phase.

Noticed a 5KVA Sola MCR on Ebay that does regulation and harmonic filtering but you have to be careful not to exceed the rating of these type, even more so than "regular" ones. Haven't heard of anyone doing a center tap on these, probably because of the price.

Rhyno,

There are many benefits to proper selection and installation of iso transformers in your system. Besides reducing noise and creating a blacker background, I have found they eliminate grounding issues and the need for any further PCs, and make the system much less sensistive to cable/wire swapping.

See my system page below and the pictures and diagrams.

Here are some keys: Balanced configuration is OK but not necessary. Iso must be iron core (the heavier the better), and rated 2-3 times your peak power demand. Follow electrical codes for a subpanel and grounding.
