Hey guys! I recently finished building bottlehead crack amp, and passed all the resistance check, but when I plug in the power, the fuse is blown, so then I check and fixed a few untrimmed wires and checked the wiring, no problem, replaced the 0.5A fast blown fuse and connect is to power, but the fuse was still blown. I did the test without the tube, still doesn't work. I can't figured out what the problem is, so I took some pictures and hope I can get some help here. Thank you so much!

Blowing fuses generally means that something is in backwards, or two things are touching which shouldn't be. Your diodes and capacitors are correctly oriented, but you should carefully inspect the power supply built on the two 6 lug terminal strips. Look for adjacent terminals that have untrimmed component leads that might be touching.
Also, get some 1A fuses, they will give you more realistic results.

Thank you so much!! Switch to a 1A slow blown fuse, and all working fine!
