Hi, my name is Doug Hoffman
The EL34, in EL34 World, refers to my alias, which I have been using since 1999.
I first used EL34 as my gaming name when playing Quake 3 at LAN parties and on
I had to come up with some sort of alias and EL34 is what I came up with. :)
A EL34 is also a very popular power tube for many amplifiers.
I own several web sites that contain information about vacuum tube Guitar tube
amps. Hoffman Amplifiers is my Web
store site for tube amplifier parts and SSC P7 LED bike light parts.
EL34World is my Main information site for many different subjects.
