Have you seen page 8?
No, I haven't been watching this thread at all. Just thought I'd drop my beauty shot in here.

What op-amps did you choose?
Ye olde 8610/20. I've said it before and I'll say it again: this is nearly the ideal battery-powered op-amp. Works fine on 9V, reasonable quiescent current, good bass, low distortion.... Its main flaw is its brightness, but the BUF634 tames that.

single silver sequin to the top of the LED
Great idea! Aside from being less obtrusive than the dime, it will be closer to the light source, so smaller is okay. It might also be interesting to leave the center hole of the sequin unblocked in order to get a small dot of light on top.

You could test it with some (kids) glue stick, or even chap stick.
I'll use what I did on the dime: rubber cement. It's sticky enough to hold long-term, but you can still pull it apart later.

use an SMD-LED instead....A 0805 fits beautifully across the existing LED pads
Interesting! Only thing keeping me from trying it is that I bought a bunch of these T-1-3/4 white LEDs back when we added a centered LED to the META42. The amp I just built is close to the ideal we had in mind when we made that feature in the first place.

My take on the Pimeta-in-translucent-H65
Nice amp, Nisbeth!

the addition of the alps switched pot lends a much more polished feel to the amp when you the Serpac case
Yeah, toggles aren't the most beauteous things in the world. And, having one less hole to drill really helps with the time. You still have to run two wires with PIMETA v1.1 though.

it makes it easier to position the amp the right side up
The asymmetry of my front panel takes care of that for me, too, in a different way. I put the input jack on the right side of my case because this amp will be going into a Headroom Mini bag along with the iPod, and I'll be using a right angle end on the amp side of the cable.

if only we had pads so we could board mount 1/8" I/O jacks
As Nisbeth indicated, the rule in my amps is only one board-mounted panel component, and the natural choice is the pot, as it has the most pins. To add more would pretty much demand custom cases, and at that point I might as well start selling kits or making assembled amps, neither of which appeals to me. I'm just a DIYer, here trying to make more DIYers.
