Tyimo, I ask myself the same question
As to your question about anyone building the ZenV9, take a look here

The sound is just amazingly good from that amp, the topend is just smooth and great
The only little catch is the limited power-rating of 2x 15 watt's. My main speakers are rated at 82dB sensitivity and my second pair are rated atn 86 dB. The ZenV9 sounds great with my second pair
Which are ProAc 1s clones
On another note, I hate to think that I am actually the only one building stuff around here??

will take a while..I'm saving up for a nice chassis from a vendor in my own little town!!!
just discovered him on the net..and the store is practically next door!!!

Hi Steen,
It's on the page as well...but I'll do a translation (just of the first sentence![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
The handles are € 32,50 per pair. i.e. not included in the prices mentioned above.

And if you are wondering: The version with 18 CM high and 30 CM deep will result in 47 degrees celcius when running a standard Aleph 5.
The largest one can dissipate 400 Watt.
Rick is really into the Pass scene. On my request he even added a 2x60V, 2x12V 120 VAC encapsulated transformer to his goodies. Great for the Kari boards!

I threw a quick ZV9 together a couple of days ago, but wasn't particulary impressed with it, so it had a real short lifespan. At this moment I'm playing around with a mutation of the ZV1 which is heavily biased and using a different bias circuit, it sure sounds better to my ears than the ZV9.

So...what are you going to do now with your power jFet's?I threw a quick ZV9 together a couple of days ago, but wasn't particulary impressed with it

For now I will limit myself to making an all jfet balanced single ended amp, something like ZV7, just jfet and lower rails.
Besides that I have planned to make a cascoded version as well, so I am actually in the market for a few more jefets, I only got like 30 or 40 of them.

Hi!
Thanks Steen for the answer!
It is doesn't augurs very well.... What about the bass and the mids etc. ?!?
Magura!
That was about I am afraid!

Stefano,
Might be helpful if you posted a diagram where to put the switches.
Simple I'm sure, but it would encourage people to actually play around with the circuit-even a little!! and that's a good thing! Especially now that circuit boards are being made and more will be building the amp I'm sure.
What are the advantages of each setting-any opinions?

XELB said:I am awaiting for my order but I think this amp needs a very good output cap and a good trafo.
Anyone have recommendations? Also, how critical are the power supply caps?
Thanks.

Thanks.
As in any amplifier, better the PSU caps, better the sound!
Remember, if you want "good DC" feeding your speakers, you have to feed your amp with "good DC"..... your amp it's committed to what you feed him.
If you always eat Macdonalds, don't expect to have good blood
![dead :dead: :dead:](https://files.diyaudio.com/forums/images/smilies/dead.gif)
In the output caps, I think I will use ELNA audio caps or Philips.
Blackgate should be perfect but they aren't cheap.
In the PSU I will go for Rubycon
And 2x 650 VA trafo
PS: Hey Veteran, don't forget me hehehehehehe
Hi Stefano!
It is getting to be interesting
Thanks for the comments.

I have mine from months , and it is my favourite zen . With some dsd recording it just amazed me . I putted 4 switches for easily convert it from current source to voltage Aleph ( and viceversa ) , with my FE206 Fostex drivers MLTL speakers . Cant stop to listen to it .

I've just started building mine. I am shocked at what 5% variance means for some of these resistors. Like the 0.47R measured as 1.1R or higher. Just surprised about that. I can mebbe post pics but I'm not sure how to. I lack the 4x15000uf/63V needed for the powersupply so any suggestions would be appreciated.
I went with the jenson 4pole for output coupling and N-type 100uf for the 220uf caps on the board.
Not very far into it, but I can take pics and such. I'm considering getting higher quality resistors for the 1.0 and 0.47 parts since the ones i install might be a bit off.

It could also be your DVM. Some can't measure low values accurately. You could measure a few in series and see if the measurement makes sense.
