you wont get killed if you use any sort of common sense whatsoever
#1 - get some dark hair dye.....
#2 - read a bit - as much as I dont agree with his business practices, the Torres book on building amps is really pretty good, its out of print, but called "Inside Tube Amps", and you can get it used on amazon
#3 - you can get a kit, or just buy the parts. Generally, if you buy the parts you'll get better parts, but pay a bit more. Kits usually have the lowest grade parts, especially capacitors, sockets etc. Get the good stuff.
#4 - ask a million questions here, take lots of pix, and there are enuf amp builders here to get you through it
#5 - when you flip that switch, and it cranks up, there is precious little equals the feeling. To me, its like the thrill I get every time I throw my leg over the Harley and hit the switch. The thrill don't fade.
And thats THAT!~
