Building the headphone amp was a merry-go-round business with ordering lots of components from different suppliers, even running to Jalan Pasar and buying op-amps and getting cheated on the price.
This design is supposed to rival expensive headphone amps, and sounds almost the same as a Benchmark DAC in blind listening tests. For more information visit http://nwavguy.blogspot.com/

Estimated Costs
 RM100 (Farnell Stuff)
 RM30 (PCB Board)
 RM10 (NJM2068D - kena conned, should be RM4 or less)
 RM 7 (2 x NJM4556AD)
 RM40 (about there, for a 18VAC AC-AC transformer)
 RM60 (enclosure)
 RM30 (machined front plate) 

 RM270 (Total)

If any of you are interested in this amplifier, I can build one for you ;)

Shots were from my A55/Tamron 1750/2.8. Still learning how to use it nicely.

More projects coming up, hopefully more stuff to show soon :)

Stay tuned.

It’s nice to have that feeling of satisfaction of making something using your real hands every once in a while. I think it’s innate in my blood to make stuff. Or deconstruct stuff.
