Nice steenoe, nice 
And after reading this latest update of this old topic - I also just couldn't resisit (altough photos are allready published in some other thread in this forum) to add another photo of brother Zen of the one you have ... Interesting to see same PCB but with different elements built in ...

Wow, Stabist yours is nicer than mine I have to admit that I threw this amp together in short time I was just curious about the sound of it I was not disappointed at all. This layout is really to be recommended, easy to build, cheap and highend sound What else can you ask for I didnt mount the pcb's directly to the heatsinks because I would end up with the 2 hottest mosfets on the same sink. I dont think they are big enough for that. So I had to make the wireconnections.
Nonetheless I am pleased with the performance

BTW, Brother ZEN can't have to many pics posted

It may not be too pretty inside, but its pretty sleek with the lid on. I made the finish in my usual style, like this:http://www.diyaudio.com/forums/showthread.php?threadid=40928&highlight= Nope I didnt turn to soap

I found the Zv4's sound closely related to its cousin the Aleph 3. The Aleph 3 having a tad more refined sound (no caps in the signal path) across the audioband. My Zv4 also was built with no exotic electronic parts. The Zv4 has better bass punch (again A3 is more refined) probably due in part to its mono design up to the AC input and higher PS capacitance.
Steenoe, paralleling (bridging) Zv4s will change its character by introducing odd order harmonics and lowering even order ones. Nelson mentioned this will make an amp less romantic sounding deviating from the signature sound of single-ended amps like the Zens and Alephs. IMO will be better for movies but not for music. Let us know of your findings. The Zv4 is also excellent with movies.

Thanks a lot for your reply, Blues As it happens, I just love the romantic sound of the ZV4
If it is true, as you said, that odd harmonics will creep in when paralleling, I dont think that I will like it! Just was thinking of NP stating, that two in parallel would perform really good. (In the Zen papers ) I do not use my HiFi for movies, and it would take a long road to lead me to that Whatever, I am listening to Black Sabbath right now
Now and then I do connect the tv, to my Stereo! When watching "Twister" The sound was great What a SPL you can get But what, I rarely care to watch a movie I Want to stare nature, right into its eyes. As you might have noticed, I am a hardcore Flyfisherman As for the romantic sound, I guess I better finish the Aleph 5 then? I did all the hard work allready. Take a look at this chassis The pic is 2 chassis I made, the big fellow was meant for the Aleph 5 The small one is doing service as my ZV4.

Blues, regarding the tools, it doesnt take a lot. A few hand tools is all thats needed. I had the alu plates cut to size at work and the rest wasnt to difficult to make. A few drill bits and threading bits, is all thats needed! Have a look at the inside of the A5 chassis, with 2 500VA trafo's mounted at the faceplate. They may seem a bit small, but they arent The Chassis is quite big and heavy.

some design emprovements
thanx kirc for single sided board
did some optimization on it

An externally hosted image should be here but it was not working when we last tested it.
some photos almost finished on that pcb

there is some mistake on kirc
the zvp legs D G S
on the thematic
http://pic.ipicture.ru/uploads/081030/Nw8HUZP4Cv.png
g leg conected to ground on the kirc sheme d or s can be conected to ground so
some changes
also notice if you plan to make pcb so that mosfets mounted on it and then it placed on rad (without wires) the kirk sheme is not usible
need to mirrow it (i maked that stuped mistake and not mirrowed)
so need to remake the pcb
the right pcb sight from the top of metal layer
if someone needs ill post the pdf version
