Finally got the case work done on my DAC (Monica 2). Thought I'd share some pics...

Overall

Charger

Toggle Switch

Basically, the toggle switch either connects the battery to the DAC and disconnects power from the charging circuit or it connects the battery to and applies power to the charger.

Very nice! A portable DAC, gotta love it!

I like the big heatsink too

Yea...it actually is portable and would be able to run for a good week before needing a charge too

As far as the heatsink is concerned...the charger puts a solid 1A into the battery, so the heatsink gets pretty warm when in full charge...

I posted some pics of my M³ and STEPS finished in the M³ discussion on Headwize DIY workshop.

Here my files are too large, sorry.

Go there, and give me your comments,

Sorry about the pics quality, poor camera, poor photograph, poor resolution due to compression!

Al the best,

GregVDS

NSSPS (Not So Simple Phono Stage.) This is based on the VSPS, but built with a CCS for class a bias of the opamps + buffers. The amp is dual mono. The PS is quasi-dual mono.

front: Sides are walnut.

inside: It's hard to see in the picture. The resistors are mostly Riken, with a few draloric thrown in as well. The output caps are Solen bypassed by Vitamin Q's. The opamps are opa627's. PS caps are mostly panasonic FM's, though most of this amp was built with stuff I had around left over form other projects.

What hybrid amp is that? One of your own design, or something else? Schematic?



Nope it was a sold piece of wood, and I used a drill press to hollow out the inside

and then used belt sander to do the sides.

The design is sijosae's from headwize.

edit: here is the schem

I just finished casing up my 4th amp thanks to you guys.

M³/Tread in a Hammond

Parts from n_maher's BOM, nothing fancy. Still, it sounds marvelous.
