A Dremel, an aluminum nibbler, a lot of time, and a couple of blisters.

Which hammond case is that?

1455N1201BK from Mouser. It's the smallest case you can get that will hold the battery tray and the PCB, I think.

Well, I got bored the other night, so finished stuffing my Mint. Not cased or split yet, and I want to take the gain down when I get some different resistors (currently at 11, want it around 4), but it works, has only 1-2mV DC offset, and makes the E2c's sound much better. I don't have any good 9v batteries (though I had one but its down to about 4.5v, really scared me when I tested DC offset and it was several hundred mV, but I ghetto rigged it with a spare Fortron 300 watt ATX PSU, running the mint off the 12v rail, and it is fine. Actually sounds better than I was expecting.

This is (hopefully) the last pimeta I build.

OPA637's on left and right channels / OPA627 on ground channel
Double stacked buffers on left and right channels / Single on ground channel
Class A bias
1000 uF Panasonic FM power supply caps.
Alps "Blue Velvet"
Vishay Dale resistors
0/75 Ohm impedance switch for output
PPA style bass boost implemented on a dip20 socket.

After listening to it all weekend, I am extremely satisfied with how it turned out.

Definitely glad to have it up and running -- now all I have to do is get the Dynahi power board to stop exploding and I'll be golden.

Come on man, thats just a normal part of burn in

. The cd player looks great, and I bet it sounds even better. What are you doing to hold the disk?

Yes, a normal part of burning-holes-in-my-wallet.

Take a look at the little deelie in the lower right hand corner of the picture that looks like a flying saucer. That's a magnetic puck that keeps the CD in place on the transport. Handy device and lovely too...definitely didn't make that myself.
