For all of the "Mo' powa' " I think you have our attention.

Cool.

I'm doing some finalizing but my hopes are to get commitments for boards by next week, so I can order ASAP. 

Have to move a few things around on the PCB before printing.

The PSU will work well with two Antipoles bottom to bottom, spaces, and L brackets. You connect the + and - on one of them to form a PG, and then run wires off of the + and - left over to the amp.

It needs way more heatsink than I have in the picture. This one can use one of those cases that has heatsink walls. Maybe a copper bar heat spreader is wise too.

The feedback can have different character based on different caps, but I think I'm settling on one that has real punch, real texture, real dynamics. It sounds good in other ways too. Another cap sounds euphoric, another is insanely refined...  :rofl:

The feedback operates either on 9v or solarcells. I'm looking at doing a DC offset prevention thing, because you can get up to .5v DC offset when the battery dies (lasts for a number of months, maybe more, not sure).

What are the caps that give the different sonic characters?

The ones in the feedback. I've settled on the one I like the most, but I will list one as an option that has interesting "euphoric" qualities. I'll list a little header plug that fits easily for swapping too. But sound is improved some by having shorter leads without a header or extra cap leads.

Jeremy,

I'm always impressed with the thought that goes into all of your boards and designs.  I'm looking forward to this bad boy.

I'll be in touch end of the week about getting one or two.

Keep it up, my friend!   :thumb:
