MOSFET headphone amplifier in Class A

I'm rebuilding this amp completely... This is past now...

This is my homemade headphone amplifier in Class A with MOSFET IRF510. I use it with my AKG K530 Ltd headphones. Yeah, I know. My wiring is always a mess. :)

u know that the switch is in wrong way round ?

@demonbreed131 Why?

[demonbreed131]

@cortkatanakx1q switches are on when they are down and off when they are up,eg light switches,control boxes and plug sockets, anyways looks like a nice headphone amp nice work

[cortkatanakx1q]

@demonbreed131 I've seen lots of headphones/guitar amps with this configuration.

you are ruining the case with ceramic capacitors

[cortkatanakx1q]

@xSlavic No. This is old version. I'm rebuilding this amp. Check my video response.

@cortkatanakx1q Down is off. Up is on.. always. Nice transformer!

@cumesoftware Thanks. But I always make PCBs, case, design and than - hell, what to do with those wires? :)

[cortkatanakx1q]

@cumesoftware I bought this metal case and cut around 2cm of it's height. And painted it with Casati spray (great quality) - can't remember how many times. Sandpaper, color, sandpaper, color, ... Looks perfect.

That is really really nice. Great job!
