No worries at all.  I do this in my spare time as a small side business to help people build their own amplifiers, and welcome criticism.  If you think the dual bridge rectifiers are a waste, I can't imagine what you think of people who build these things using $5 each Mil-Spec resistors and $50 each capacitors

Joe,

Sorry for the delay, was out of town for work.

Here is a schematic for the board:

As for the CT transformer, you will want to remove the center four diodes, exactly as R.G. described.

Let me know if you have any more questions,

BTW, the LM1875 kit that I sent you has been available for quite a while on my site.

-Brian

I hope all of you enjoyed the free kits

I prefer the 2x25vac avel transformers, and use a 330va one for my stereo 3886 amp.
