DIY tube amp?

by Chris Randall

Is anyone aware of a simple single-tube amp project out in the interwebs? I'm interested in trying my hand at building a simple tube amp, and I have some excellent NOS GE 6L6 tubes that'd be perfect for the project. Plus I want to know what it feels like to get hit with a 480V shock.

Guitar amp? Mic preamp? I assume it's a guitar amp with the 6L6, but don't you need at least 2 tubes (preamp tube & power amp tube) for a guitar amp? As mic pres go, here's a single tube one:

For guitar amps, I suggest cruising over to They're all about building 18 watt Marshalls, and there are kits available. It's on "the list," but after my desk and SSL compressor. Maybe a mic DIY will sneak in there as well, and the Minimoog and API EQs if they ever happen.

I've wanted to build something from the ax84 project for a while.

Some of those use 6l6 or 6v6's

The 18watt project is highly regarded, but IIRC those use 12ax7/el34's.

Actually, in thinking about it, I reoriented my Plan Of Action. I have an old Victorian tube reel-to-reel that doesn't work for shit. At least, the mechanical part didn't work for shit. The amplifier sounds fantastic. I've just taken it apart, marvelled at all those pristine-perfect 50s Telefunken tubes, and ordered a 10" Jensen.

The reason for this is, of course, my desire to build a recording amp. I have a nice Vox AC-15 for said purpose, but I was thinking it would be pleasant to have something a little less... uhmmm... British?

Anyways, after puzzling out the mute switch on this reel-to-reel (which is a three-decked 24-point spring-loaded affair) and hooking the AC-15's speaker to the output, and annoying the neighbors for the last couple hours, I've come to the conclusion that this thing sounds like the fucking bomb, so I'm not going to bother with building one from scratch. This way, all I have to do is build a cabinet.

Weber sells some great amp kits and even has links to other kits from their website.

oh yeah, they have all their schematics posted if you want to source all your own parts.
