Hello! Awesome project, I've made mine but it isn't working. When I try to make fuse bits i get an error, I'm using an atmega 328p(did the same with a 328), WinAVR and my usbasp is connected to the programing header. What could be the problem?[code]avrdude: verifying ...avrdude: verification error, first mismatch at byte 0x0000 0xfc != 0x04avrdude: verification error; content mismatchavrdude: safemode: efuse changed! Was fc, and is now 4Would you like this fuse to be changed back? [y/n] n //If I put in 'y', than it just freezes in that position until I disconnect the programmer.avrdude: safemode: Fuses OK[/code]

This only works with Nvidia tho... Any alternatives for us AMD users?
Firstly it didn't work for me.. I didn't see my error and I was certain that everything was good... I even had my pops look at it to try and figure out what was wrong, and when I realized, after 2 days, that I wired the tube backwards.. :\Luckily the tube survived and now it's working pretty good! :D Now I'm just having trouble finding a good power supply for the damn thing, I might just end up using a 12v battery. :P
Probably not connected properly. I had the same problem, and then I looked at the datasheet for the tube and realized I had accidentally wired in my tube inverted :\Luckily the tube didn't brake, so I fixed my circuit and had a working tube amp. The tubes pins, from the slot increase cw. So if you have the tubes' slot facing up it goes to the right.HOWEVER if this is not your problem, and you are certain that you have wired everything correctly, then try removing the tube and try seeing if it draws current that way, if it doesn't then there is something wrong with the lm317. If it does, and you have a properly wired circuit than it could be a faulty tube.
