Getting hold of an Cooler Master Elite 361 next week and rebuilding the rig into that. Will test and post findings. With the PWM Buck-converter designed by jvjessen (hacked into an old stiffy chassis on top of the HDD's) I was able to get all the temps down by at least 15'C. So now @ idle/watching movies CPU/GPU/HDD = 20'C-30'C and noise is minimal, OC is much more stable and temps are way down! Have been able to OC my Phenom II x4 965 BE @ 4GHz (24/7) stable for the first time ! Thanx dude!biggrin.gif
The setup:
Phenom II x4 965BE @4GHz
Kingston ValueRAM 2x2GB DDR3 1333@1600MHz
Sapphire Radeon 5750 (BIOS Flashed to 5770) 900/1350MHz
2x250GB Seagate 250GB SATA2 RAID0
1TB Seagate
40GB IDE Ghost Image of RAID0 for instant restore
OS: Windows 7 Ultimate x64 (on RAID0, terrible to install but worth it! Damm Microsoft!)
Thanx again for the support mr jvjessen!

Thanks smile.gif .. I'm really happy to see the circuit being put to good use smile.gif

Nice work on the clean wire management thumb.gif looks really good.

Thanks for the comments! Couldn't have done the stable overclock without ye! thumb.gif

Understand you, I'm all for efficiency, but actually when you look at the big picture the efficiency is pretty good, qualified guess based on random measurements is above 80% at 15-20W load. So not bad at all for the low complexity, but surely higher efficiency can easily be achieved with a bit more complex circuit smile.gif

Those two next to it are are push pull tube mono blocks, they are actually quite large, but they seem small compared to that amplifier smile.gif..



The big amplifier is chinese made based on, I believe famous Swedish design, it's named JungSon JA88D-09. It's one of the high-end finds of the century (IMO)... It's great and reasonably cheap as long as you are willing to deal with the heat and power bill it generates smile.gif

It is however no worse than the SE 300B 6W monoblocks above them, consumes 75-80W each and only got max 6W output (1% distortion), but magical with the right speakers:



Sorry, you got me started on my other hobby biggrin.gif

NICE! Last time I saw so many valves was in a picture of ENIAC! hehehehe! They do make a greater noise (sorry noise is it NOT! I should have said sound!) #11 Glad to see some one is keeping them alive! Been looking for some pre-amp then amp ideas for portable mp3/acc/flac players based on valves. Not for carrying with you but plugging in at home like those crappy docking stations you see in cheap electronics stores! only better! Any ideas?

I have a personal affinity with NAD amplifiers! I love their mono block, mono channel design and dont think it is over-kill! Flashing lights and the like just draw power from the amp and does not contribute to sound! But I suspect this conversation might be meant for another Forum/Thread!

Hehehe.. yeah, you are right, valves are not common, but they do have some qualities, objective or subjective I cannot say for sure. but they sure are more difficult and expensive than transistors smile.gif .. Some of my amps use tubes that haven't been manufactured since the late 1950's so they can be very expensive to replace, I guess listening to them is a bit like drinking a vintage wine that cannot be replaced.

There are actually many valve based headphone amplifiers available, whether or not they are better than op-amp or transistor based I am not sure, but they sure do look pretty biggrin.gif

Even with all my valve amps I have to admit my favorite amplifier is not valve based, but I believe that is mostly because my main speakers are not valve friendly (tube amps usually have much higher output impedance, so low impedance speakers will change characteristics with valve amps).. I am working on a project to create the "perfect" speaker for low wattage valve amps, not sure this is the correct forum to post that in though smile.gif

I am from a well known wine region so can appreciate the analogy! wink.gif Great stuff! I am also trying to keep the past alive with a P1 project complete with 15"CRT I'm keeping alive for prosperity! I can just see the beginnings of a speaker in your last pic, can you post a pic of it please?

I am interested in the power-supply side of your mono-blocks. I have some circuits but they are quiet old and I have not seen them implemented.redface.gif As I have some experience with your circuits I would feel more comfortable trying them out.biggrin.gif

Yeah, NAD is a great brand, they have a made many great amplifiers with their unique designs. but yeah, I think you are right we are drifting off here smile.gif .. but I usually say as long as it's interesting, cute or shocking it's never off topic biggrin.gif .. moderators might disagree though redface.gif
