Personally I would want the extra headroom with the 24V secondaries. Because the amp is really best suited for 8ohm loads. So voltage headroom will be desirable. That said, 22V would work fine too.

IIRC the Voltage required for a specifically 4 Ohm load was 18V. pri.?

Is this correct?

So Russ says he would prefer to have a 24VAC toroid but that 22VAC would be fine to.
I suppose I could ask John at Antek about the option to have a discount on how much we buy rather than how many we buy that way we could get either 24 or 22 based on what people wanted. We will see. Give me and Peter a day or so to get it sorted.

My Bad!

I did a little looking around on the original thread, and I think my previous reference was regarding a straight chip amp with the LM3886 only, and 4 Ohm speakers.

Sorry.

John

I am back from vacation and am willing to bundle a
package for this project and will work on this as soon
as I'm caught up...
Being a one man operation is not as easy as it used to be.

I do have all the items needed to finish this project
and will look into a project box too.

I will notify on this thread if I can find a suitable chassis

Steve @ Apex Jr.

Peter, Uriah, Russ and Brian-

Am I correct in the PCB size being:

Board size w/o heatsink (from earlier post):
4.115" from back of LM3886 to front, 3.27" wide,
2" high (2.5" incl. standoffs).



I got that off of a post on the Twisted Pair forum (Thanks guys for keeping the legacy product support up on the site!)

Troy,
I think you are about right. Mine is 1.8 inches tall and about a tenth of an inch shorter in length than you said.

Welcome back Steve. Hope it was a relaxing vacation.
