Well, I want to learn more about amps and building them. I'm thinking about building a hoffman 6v6 plexi because they are very well explained, simple and they seen to be a nice platform to start experimenting with some mods. If you think differently, please let me know. I think my "final goal" will be this small plexi with a loop and a gain cascade mod. For now I have no idea how to do some sort of "one cable mod" in this amp because it has only one input. what are your thoughts??? build example http://el34world.com/schematics.htm#Plexi_6V6_build schematics https://el34world.com/Hoffman/files/Hoffman_Plexi_6V6-V2.pdf any inputs are welcome, and I'll try not to kill myself building this amp.
