It looks smaller than the M3 proto. The revised PCB he used is the same one outlined at diyforum.org.


Nice work, Amb. The acrylic end panels are pimp.

The Millett is smaller than my M³ proto. It is just a bit taller, but the width and depth are both smaller. Here is a pic of three of my amps together showing relative sizes (from left, clockwise: Modified SDS Labs amp, Millett Hybrid, M³).

I haven't done much comparisons yet, should be interesting to do that. I'll be bringing all these amps to the San Jose meet so you could have a listen yourself.

No. The "revised" refer to the board design from n_maher and drewd rather than the original one from Pete Millett (which is sold via diycable.com). The circuit already has a form of reverse voltage protection. If you look at the schematic, there is a self-resetting fuse at the DC power input, and then there is an protection diode across the supply. This diode normally has no effect, but will conduct and cause a virtual short if the input DC is reversed in polarity or if the voltage is too high, and that will in turn cause the fuse to open.

This is a Gilmore Dynamic that I finished other than the faceplate last spring. I am very pleased with the sound of this, driving a pair of AKG 401s predominately, and also some Grados. I think that it compares quite favorably with the Dynahi's that I have heard, as well as other amps (Raptor, etc.). Parts include a mix of Roederstein and PRP resistors, Nichicon Muse FX and Wima caps in the PSU and a TKD 2CP2511 pot. Jacks are Cardas; phone jack is a Neutrik ReAN. The PSU portion of the pic also shows the two PCBs I designed and etched to replace the packaged rectifiers used with 31DQ10 Shottky's. I'm still trying to decide on how I want to do the faceplate, so I just cut a piece of plexiglass to use for the time being. I am also going to add more inputs with selector switch, and an Amb relay board to mute the preamp output.

here are my first build Steps + Millett Hybrid come to the final stage completed.

 

[Thaddy]

James281...that Millet + STEPS looks really sweet man...but uh...you kinda spelled 'Hybrid' wrong

 

[philodox]

Very nice work James, I especially like the curved silk screening around the Headphone out. The clear tops look great.

atleast it is a funny typo... well atleast mullets are funny

haha i can't believe i screw that up, ohh well i can still redo that

My first Chu Moy has finally got a smaller brother. The big brother is broudly in the first picture.

It's less than 60x60x20 millimeters (exluding the knob).

Unfortunately I made a small mistake with it. The input jack is too close to the knob (even though I did try to plan it). Luckily it's pretty easy to have another case.

After solving my STEPS problem, I've done some heavy testing and casework, and here's the build at a soon to be complete stage.

The Millett board is the original board, with a few alterations in components. Caps are Blackgate standard series (Welborne was out of the Elna's, so I had to upgrade

), input jacks are Cardas cheapies (relatively), I have a neutrix headphone jack not wired up yet. The Linkwitz board uses Roederstein resistors and Wima caps. The case is an old Appletalk case I found walking home from work. I cut an aluminum bar for the jacks on the back.

Once I get it all put together, I'll post the finished pics.

Hey, anyone else with this build: do you need to run a wire from the Millett board to the case ground?

Cheers

The result of this weekend's labour:

PPA v1.1 with copper front panel:

Guzzler's USB-SPDIF board:
I couldn't decide on an enclsure for this one, so I took the easy route

With power on. They weren't lying when they said this LED was "hi-bright"

/U.

 

[jerb]

Great Idea with the Guzzler DAC, been meaning to get around to mine but theres no way I could solder the little chips
