Hey AMB....very nice looking build as usual. Is this physically the same size case as your M3 Prototype?
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).
In listening trials, how does the 'ease of listening' compare to the M3 which I find wondefully non-fatigueing for extended listening periods.
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.
Does the revised PCB incorporate the Diode modification to protect against polarity reversals discussed at the DIYForum.org ?
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.
Very nice work James, I especially like the curved silk screening around the Headphone out. The clear tops look great.
