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.
