Be sure to grab that pdf when you get home.
hi michael , i actually enjoy l'amp fig 11 with a bypassed source resistor , can i keep the same config with the inductor load?
where to find a source for this heavy gauge air-core?

i can't imagine this thing can sounds even better with CSS or inductor load ?!
amazing!!

Well, you'd need even more source resistance to set the operating point properly. It doesn't seem like a particularly attractive idea to me, but you should follow your heart.

Eventually, you'll want to get your voltage references working. These really shine with no degeneration, and I think you'd do well to focus your effort there. I have, after all, posted a working schematic which you can easily build on perfoboard.

Would a PCB sway you?

so for you : first choice is inductor load , second CCS load and third bulb/resistor load. and last my config resistor load with source resistor

i'm out again ...

that's why i have to learn .. so i will repair my bias module and try again with it, so just have to change the power transfo from 40V 800VA to 28V 400VA and try CCS first, before i could find an big 100mh aircore somewhere..

I think the bulb versions and the inductor version are somewhat similar. The inductor version has the advantage of being quieter, more efficient with higher power, higher gain, and no turn-on thump (but it doesn't glow in the dark).

IMO, the CCS versions come in after that.

At least until I change my mind.

I will say this: I keep going back to the inductor vesion despite the fact I have to lug them up two flight of stairs to my listening room.

I'm not sure why this is, but that's the data.

I assume you're not talking about the energy required for me to carry them upstairs.

So now my curiosity is piqued. I hope you'll elaborate.
