Zen Variations 5

Nelson Pass · 15th July 2003, 08:53 PM

I think I'll just start this thread, now that ZV5 is up at
www.passdiy.com .

It's in tiff format at the moment, but Mr. Harrington promises a PDF version in a day or so.

Neat. Thanks again as usual for very interesting reading. My A30 is not in operation yet but the chassis is just waiting to be used for something. Can't wait to get back home after vacation...

Indeed another very good tutorial explanation!
Also I easily imagine the good sound of ZV5.

I'm looking forward to trying one of the Zen variations. . . just as soon as an Aleph gets finished. When I started viewing this forum, I noted the Aleph buzz, but now it seems to be a chipamp buzz. I can understand the implicit simplicity of those projects from a beginner's view and have even built on myself. But, I really hope to soon be able to hear a real class A design, both Aleph and Zen.

Thanks, NP, for helping keep high-end DIY in the reach of beginners. I am completely ignorant with EE designs (getting the occasional headache trying to figure out what the heck the guys in Audio Express are talking about) but the well written designs you publish help me to keep trying and understand a little more.

Thanks!

Sandy.

Being relatively new with the Zen amp, I'm very keen to embark on this project. Is it possible to re-use the original Zen PCB to construct the ZenV5, as I have 1 pcb which I bought it 2 yrs ago and isunused.

thanks.
will.

What about the point-to-point?
The circuit looks easy enuff for it.
Probably Passdiy offers PCB soon?

I'm, also, really fond of that power supply you've drafted out for us.

Many thanks to you and your crew,

John Inlow

Thanks Nelson! Great Article.

Can one transformer with dual secondaries be shared for 2 channels, while still replicating the rest of the power supply components?

What is the ETA for J-Horns mentioned in the end of the article?

Thanks Nelson,

Nice reading, nice big power supply, but I missed some pictures of your prototype. I like very much the ones showed in your articles... inspiring

I was hoping for cascoding, susy, only half gain device, fluorescent loads, sensorial biasing or something like that, and I get push-pull !!! Another surprise, hail to Nelson.

BTW, which range covers the best this amp? bottom? midrange? top? Yes, I'm still waiting for the xover...

Good stuff, as usual! I was surprised to see the dissipation on the mosfets was so high. Do you think that will be a problem? I was also surprised that it didn't use a follower output stage, but I guess that wouldn't be in the zen tradition. Thanks for the interesting reading.
