    I want to get back into electronics and thanks to Tension I now have some very decent test equipment.

    I was looking at online guides to building head amps and came across this

    I like it because it has been 12 years since I have properly studied electronics and I am now very rusty so I would not confident of designing my own PCB from a circuit diagram.

    But is it cheap crap?

    I would use it as a portable headphone amp for my Samsung Galaxy.

    Under 'A Pocket headphone amplifeer' is the original article being ripped-off.

    Chu Moy originated 'Headwize' and the library remains full of good advice for easy (and not-so-easy) DIY. Have a good read , and have a go. Chu Moy's basic amp is a great jumping-off point for all sorts of reasons. Not the-greatest-evah, but it remains simple, reliable, and essentially sound. You can find pretty much all you might need at Maplin for bobbins.

    Looks like a nice simple design, although I'm not sure how good the NJM4560 opamp is. The Behringer stuff I modify uses the 4580 which looks to have a similar internal schematic and it's got some nasty IMD products. I might suggest trying a NE5532 as a replacement. It is also commonly used to directly drive headphones such as in the Behringer SRC2496. Someone more knowledgeable might point out why the 4560 is better.
