So the M+ and M- connections are just for series connections?

(Otherwise...gee, I guess both wires will easily fit in the V+/V- holes with some solder...

)

[edit] For what it's worth, I use true 9v NIMH rechargeable batteries for my power supply, but had no issues using 9v alkalines for a time either. Hope that gives you a slightly different perspective. Nate

Your pot looks like it is mounted in the center of the panel, (not offset). Is it mounted on the board? (And which Hammond case are you using?).

It's close, but not exactly in the center because I left the pot board mounted. It's off by about an 1/8" of an inch I think, but I haven't built one of these for a few months now so I don't know for sure. Here's a pic that shows the offset a bit better.

And I'm 99% sure that's a Hammond 1455J1201. It has a ton of room inside but for me was still small enough to be my portable. And it's just so much easier to deal with than the two smaller hammonds which both have a fixed top and bottom where the J12 has a removable panel.

HTH,

It is possible to fit two 9V batteries along with a MINT amp into an Altoids tin with the pot sticking out the end. It is indeed an "L" configuration. I don't have the amp I built this way with me, but here is as best I can remember/describe it:

Halve the boards. "Mount" the amp board at a right angle to the power supply board so that the components are facing in. I think the PS board went in upside down in the back left corder of the tin, with the amp board against the back of the tin, but I could be wrong. I remember there being a couple ways to configure it. I have both jacks and the power switch at the other end. I did extend the leads going between the boards one board width, but that may have been more convenient than necessary.

Insulate everything using electrical tape, and if you use solid core wire, the stiffness of the leads will practically be enough to hold everything in place.

Good luck! If that doesn't get the idea accross, let me know and I'll hunt down a digital camera to take some pictures.

I'll chip in the other 1%. It's the J1201.

Yeah, I wonder who came up with that panel layout?

you should use the AD8620. it may be more expensive, but in the long run you'll recoup that cost by saving batteries. in my mint, the OPA2134 clipped like hell at 7.5v, but i switch that out for the AD8620 and not only is the sound much better, the amp has no clipping even down to 6v.

Here are photos of the arrangement I used, and described earlier.
