Help with oddball 3XEL34 output section?

[jbefumo]

Hi All,

Recently got back into hobby electronics after many years and am setting out to build a guitar amp. I've built several tube amps in the past, but always by following a proven schematic. This time I'm looking forward to trying my hand at a bit of designing as well.

Discovered MultiSim, and am in the process of modeling my dream amp before breaking out the soldering iron. (Amazing program, btw).

Anyway, I discovered this somewhat oddball (to me) design, and have been playing around with it in the simulator. Here's the design: The Tube CAD Journal: Out of Control: The missing sonic controls

I've got the simulation working, however, the RMS of the output signal is about 1/20 that of a standard EL34 Push-Pull output.

My electronic chops are a bit dusty, and were never that great to begin with, so I'm trying to work though this design on my own, but any hints would be greatly appreciated. My main questions are: Is this low output an inherent aspect of the design? Or do the component values need to be tweaked?

Second, any comments about how this might actually work in a guitar amp? Sounds interesting in theory, but I kind of wonder why nobody else is using it?

Thanks.

Joe

Is it the 09 January 2002 "Missing Sonic Controls" ?
