I have now changed the 0.1uF film caps to 100uF electrolytic ones, and it all seems to work now! Thanks for that! BTW, is there any downside to using electrolytic caps instead of film caps here? I'm not going to get my hands on any right now, but I might order some when I start ordering stuff...

The only other caps I have are 100uF and 220 uF electrolytic caps. Would that be a problem? Also, I've wired it point to point in a stiff cardboard-type box. It crackles when being moved and sometimes the right channel cuts out, which I can temporarily fix by tapping the amp. Tubes also crackle...

Can't figure out how to post pics right now, linking from imgur gives me an error message. Maybe because I don't have enough posts. I used Logistics' schematic (only changes being the mods). The output caps are electrolytic ~400uF ones. Actually, I'm using 3 capacitors wired in parallel for left...

I know I'm a bit late, but I recently built my first Starving Student with 12SR7 tubes instead of the 19J6. I swapped all the capacitors and resistors according to a schematic I found here. Did a couple modifications (adding a 3.5mm input and changing the Pot to 100k since my 50k was faulty on...
