I've been reading various threads on this site about diy amps and want to eventually build myself a nice desktop tube amp.
So I figured since I know nothing about reading schematics and my only soldering experience is from repairing usb cables that a good way to start out would be to buy a breadboard and build it on that.
After I finished building the power supply I tested it per tangents website suggestion and got 4.5v from both test spots so I proceeded with the rest of the build. I used all his recommended components with the exception that I forgot to buy the 9v battery clip, one of the stereo jacks disappeared on me, and changed the gain with I think it was a 2k resistor so from 11 to 6.
So with the amp "finished" I plugged in my Ipod to input and my old HD202's to the out. I can hear music but it is very low out of both channels with some crackling and after turning up the volume the crackling gets louder and worse.
I have looked over the way I put it together and can't seem to find out what I did wrong although its probably something really obvious as this is the first time I've undertaken a project like this.
I just now checked the v+ its 1.968v v- is 7.04 not sure if that sounds right after the build is finished. As for the right output I get .65v and for the left out I get .631v

Any help or suggestions are really appreciated, this noob is trying to learn.
