For audiophiles and DIY hobbyists, this amp is the mecca of affordable bang for buck audio awesomeness. This amp can be built for dirt-cheap with great results. Don’t get me wrong, there are better amps out there that are more fine tuned to you and your listening style, but it comes with a very hefty price tag. For those of us still wanting great sounding audio and a low price tag, this is it. Let me introduce you to the "Starving Student Millet Hybrid" tube amp, or abbreviated as the SSMH.

Instructables has very limited information on headphone tube amplifiers. So I have decided to help fill the gap and hopefully inspire some other builders and audiophiles. The build I have chosen is the “Millett Starving Student Hybrid Tube Amp”. Reasons being, it’s cheap (can be easily done for less than $125 for all materials except tools), sounds great, has a simple circuit and has an almost cult like following. Online support for this amp is huge, which makes questions and troubleshooting a lot easier.

There is a surplus of information about the schematic and how to wire the circuit online. So I will attempt to give you the resources about the building process excluding the schematic.

I would like to thank Pete Millett for his development of this amp and schematic. He is a brilliant and generous man and deserves credit.

Do you have a schematic?
Do you have the exact model number on the Hammond box? It looks like the larger one, but its hard to tell. 1590XXGR maybe? 154x121mm?
What does the yellow part mean? do they i have to add them to the circuit or i have to change them?

Great project! Try to make the links work in your instructable. It makes looking up the extra info so much easier for us lazy people ;)
