Nelson Pass seemed to think I did a really good job on it and complimented me on being brave enough to build something like that on my first attempt. Everybody that's heard the thing wants something that sounds that good because it really is a very good sounding amp. My efforts in tweaking it to sound it's best have included splitting the mica insulators down to .0007" for the best thermal transfer between the heatsinks and the MOSFETs, trying different input signal wires, trying different ground routing, working on getting the bias higher, and adjusting it's distortion character. I've put a lot of time and listening into getting that thing sounding just right. The signal goes through 2 JFETs, 2 MOSFETs, and 3 resistors before it gets to the output posts. If the theory is that simple circuits produce better sound, you don't get much simpler than that.
The last time I bought a multi-outlet extension cord at Walmart the thing had a gigantic warning label zip-tied to the thing. Even those cheap 6 foot, 3 outlet things often have fuses I don't think I have a single power strip that isn't fused or breakered. That strikes me as responsible engineering.
