Flash back to mid-2017 and you may remember the super cool "NuHybrid" Headphone Amp that Pete Millett designed around the Korg NuTube. If you're not already familiar with the NuTube, the current model is called the 6P1, which is a thoroughly-modern, dual, very low power, directly-heated triode...

My Millett "Starving Student" Hybrid headphone amplifier, sitting atop the Audio-gd NFB-12. The enclosure I used for my MSSH is almost the same size as the NFB-12. It's the Hammond 1455T2201. I installed orange LEDs inside the tube sockets, but I used low intensity LEDs so they are useless. The tube

My Millett "Starving Student" Hybrid headphone amplifier. The whole circuit was built using Point to Point wiring. I designed and built a 48v linear regulated power supply for the amplifier. The transformer and the cubic heat sink beside it are part of the PSU. I built Faraday cages around the tubes

My Millett "Starving Student" Hybrid, complete and working circuit. I designed a 48v linear regulated power supply for this amplifier, it consists of everything behind the tube sockets.

Finished reassembling the wiring for the tubes and the MOSFETs. This time the original layout was recycled. I also installed the back panel and some shields.

Finished assembling the power supply in the new enclosure. Since the case is shorter than the clear plastic one I had, the original layout did not fit. I rebuilt the power supply from the ground up. I placed the capacitors so they shield AC from the rest of the circuit.

Line in is wired using braided solid core copper. Physical power rails using 18 AWG solid copper. The 4 power decoupling capacitors are Nichicon ES MUSE.

My freshly finished SSMH on it's first test drive. View of the interior. The output coupling capacitors are Elna Silmic II. The inter-stage coupling capacitors are Mundorf M-CAP MKP Series.

My freshly finished SSMH on it's first test drive. The pot, knob and output jack were salvaged from a vintage stereo. There's bad scratching sound from the pot, I'll have to find a better one.

AC side of the power supply is wired. This build doesn't use all the transformer's tabs, but I still kept them just in case I want to re-use this transformer in another project. The blue wires are a 6v secondary, isolated from the main secondary, that I will probably use to power LEDs in the tube so

A thread seems to have disappeared about a new millet max design that is smaller than the last. Anyone know where it went?

Just thought I would post a quick pic of the reason I am still up tonight. Just having real trouble turning Opeth's Deliverance CD off. Had a bit of trouble with way too much gain and getting the volume knob too high with my KSC75's earlier tonight, and even with my HD580s, I cant even make it a...

Hi there,   I did a lot of reading lately (great forum btw) but still cannot decide on what amp should I get for my HD650. The biggest decision factors are:   1. I have around $350 to spend. 2. I have sensitive ears, esp to high frequencies and high volume. 3. I like deep, extended...

I've come across a couple other threads on this topic here, and have seen amps like the Little Dot and the DarkVoice mentioned.  I wanted to see if there are other options I should be looking at.   Right now I have Millett Minimax and an ASL MG Head OTL.  I'm going to have to give one of...

Been looking around for amps that can be self built and are sold in kits. I'm compiling a list, so please post if you know of any that aren't mentioned. Thanks! Solid State Jaycar Electronics Stereo Headphone Distribution Amplifier // £10.25 AMB Labs Mini³ // $88.92 AMB Labs Beta 22...

So I have some Beyer 880 250 ohms coming in tomorrow and I desparately want to put together my rig as soon as possible.   My problem is not only do I not have a DAC/AMP ordered, I haven'f even made a shortlist of dac/amps dspite hours of research.     I think i'd like to get a darkvoice...

I have a Millett Max that I want to swap out the volume knob on.   I see that most stock and eBay knobs that fit on the Alps pot are using a set screw.   What if the object to be used as a volume knob does not allow for the set screw hole to be drilled?   It could be a rock, or a...

Thinking about picking up a pair of DT880/600, but I know that they need an amp to sound best. The price ($300 shipped to Canada) is already pushing my original budget beyond what I hoped to spend, but I figure they are probably worth it instead of buying something cheaper (like the SHR840s...

EDIT: I think I've narrowed it down to one of these three, but can people comment on one of the three amps in title (or 2 or all) :-)     I already own the TTVJ Millett 307a but I want a secondary amp with a very different sound signature:   Pricerange: No more than 4k please note...

Hi Guys, done some research and it seems i've narrowed my amp choice to these amps... i guess the ppa v2 and m3 are meant to sound pretty similar, but i will likely use a wallwart first before committing funds and time to an ext power supply. q is... seems all these options will cost...
