Wow, what a beautiful-looking project website... I'm even more tempted to ignore others' advice to do a Pimeta first and skip directly to this.

Fantastic work Tom. Thanks for the wonderful information.

Looks great Tom! I think we are going to see a lot of Maxes in the future.

I have to go ahead and chime in to sing the praises of Tom, Colin, Nate and the rest of the Millet MAX team...absolutely great work, guys! Thanks for putting in the extra effort to make the MAX something that pretty much all of us can build and enjoy!

Very very impress website. Bravo for the excellent job.

I will buy one!

I am stoked. Ordered all parts that were available from Mouser today. Will order the extras this week. Can't wait for the PC boards!!!!!!!!!!!!

I will leave this one to the rightful individuals that made the max possible. I'll enjoy being the receivers' end this one around.

Just lovely

I am a big fan of the Millett and really appreciate what you guys have done to keep it alive.

Although Colin did a great job with this board, giving us a clean and open layout, debugging it if something goes wrong could be a problem if you do not have a lot of building skills. Mainly I'm thinking about the diamond buffers, which are intrinsically no easier to debug than a PPA, which can be a bear to debug (based on what I have seen on various threads- ask Nate), but also the fact that the power supply is very integrally tied into the amp. If you have a short somewhere, for example, you can't even easily pinpoint it between the PSU and the amp, as you could with a Pimeta which requires some sort of off-board power, either battery or a Tread type AC supply.

I'm not saying don't build it now, and you certainly should get your boards now when they are available, but I personally don't think this is a good beginner project for someone at the level of just considering a Pimeta, for example.

Just my very HO...

Neil

I'm going to nip this one in the bud, there are no plans to market T-shirts. It's sort of an inside joke amongst some of us.

I agree very much with Neil. I don't know if you remember Neil, but last year, you helped me out troubleshooting last year with my first Millett. I had only built a CMoy at that point, and it was tough just doing a regular Millett, let alone a maxed out amp with MOSFET buffers. I think maybe you should build a PIMETA as a nice portable amp, and once you are comfortable soldering and with theory, then move on to the Millett. Definately join in on the group buy though!

Start selling t-shirts and they'll make you a member of the trade!

Actually, they probably would.

Will anyone be selling matched transistors or even entire kits?

Also, do you have to choose between the diamond buffers or MOSFETs? If so, what are the differences in sound?

I don't think there are any plans to sell complete kits, although the majority of the parts can be aquired from Mouser, minus Alps pot and some other things. Yes, you can either have the diamond buffer output stage or the MOSFET stage, not both. I have the MOSFET version, the second one to be built, behind Neil, who troubleshot the correct parts list for it. I can't comment on sound differences as I've only got the MOSFET version, but it sounds pretty sweet to me. You can get matched MOSFETs from AMBs site, which is what I did, along with the volume pot.

One technical advantage of the MOSFETs is that they can be biased much higher than the BJT diamond buffer. I've got mine set at 250mV or about 114mA current on each channel! Bodacious!

Others can probably add more to this than I can, but I hope it provides a good start.

DOes anyone have a source for cheap multimeters that have hfe testers?

Edit: I usually call it β rather than hfe
