~6SN7 and Octal Equivalents Reference Thread~ THIS THREAD IS BEING BUILT AT THE MOMENT My original plan was to start with a very complete thread, but I kept running into inconsistencies with my findings. Over the next few days I still plan to add a large amount of scraped data, but with...

I found this info on several website reporting the Canjam (kind of) in Japan happening right now. It is called ACRO L1000, a prototype unit of a desktop DAC/Amp. And it is designed to be placed on the left side so that users can use mouse on the right side. Headphone jacks are on the left side...

I'm wondering if it's worth the money for maybe a $100+ Mullard or would I be better off putting that into a better amp in the future? Like if I add a $100 tube to this $100 amp will I get a $200 amp or is that too much makeup on the pig? Has anyone done this and was it worth the money? I...

Hi, I currently have a Schiit Magni 2 Uber, a Little Dot Mkiii and a Sound Blaster Omni (USB sound card). My Upgrade path so far has been from a budget USB gaming headset, then the Sound Blaster with various headphones and most recently the Little Dot and Magni. While I'm finding the Little...

I have a small dilemma. I will most likely be purchasing a Focusrite Saffire 6 soon in order to have an interface that I can track guitars and MIDI into from my desk at university. However I read some calculations that suggest a MAXIMUM of 240 Ohm cans for this amp. If I was to purchase the 32...

Single Ended Class A Headphone Amplifier

Matrix M-Stage amp on 18 or 20 db gain

I think I got a soft spot for black and white.

The final iteration of what started as a Millett "Starving Student" amplifier. More than 2 years after the start of this project, following countless redesigns and rebuilds, this amplifier is now much more than a Starving Student. (The price tag alone makes it everything but a Starving Student.) A p

Woo WA7 DAC/AMP

Schiit Lyr and Schiit Bifrost

For the first time in half a year since I began this project, I am listening to music trough the MSSH and actually enjoying it. The noise level is now low enough to be forgotten even with my most sensitive headphones. I concluded the MSSH and the NFB-12 hate each others, and they will only be happy

Debugging session in December 2012. There was dirt in a tube socket, which allowed arcing between pins.

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.

Exploded view of my Starving Student. Everything is painted and ready for final assembly.
