Ahh the defense of the snake oil peddlers, measurements can not capture the true glory of my cluster fuck. They simply have transcended the laws of nature at this point...

I wasn't hoping for much but one is ever so curious. Could be a variation of the same circuit King Sound uses in the M-10 and the sockets might be the King Sound units as well. It's hard to tell with any certainty but it appears to have the same textured finish. Looks like a version of this design: http://www.ebay.com/itm/2609-Full-aluminum-chassis-Preamp-box-Power-amp-Enclosure-Case-DIY-/400526703642?pt=UK_Sound_Vision_Amplifier_Parts&hash=item5d41407c1a There is also the 2607 so this could be the 2608...

So they aren't seeing the scratches? That's fucked up but I wouldn't be surprised that they are looking at the wrong set. Anybody know anything about this one? http://item.taobao.com/item.htm?spm=a230r.1.14.129.3xZ4Zw&id=36525626565

Happy New Year!!!

Get well soon Ken.

I have a pile of PSU and Squarewave boards here that I'll probably never use. Just PM if you need a set. No KSA5 though or at least I don't think so.

While the amp is stable into 8ohms I'd recommend proper power amp for this role. The PSU is always the bottleneck so dual S22's with big heatsinks are the bare minimum. Personally I'd just build a F5....

on the mosfets... So the trick is to take a device which is wholly unsuitable for the job and use it in a circuit which looks like something Stax did in 1972. I appreciate the effort but no way this thing works well when somebody actually builds it. Ohh and can somebody send me a text pdf that isn't corrupted...

The "serial label" I find funny...

90% of my cases come from modushop and they are great to deal with.

The minus rail really likes to meet ground in a violent way. Lift up the caps (I use m3 nylon spacers) and all resistors and you'll be fine. Also... flux on the boards is a big no no.

Now that I've looked over the files I'd recommend highly against using this. Works just fine but it has all the problems of the first run of KGSSHV psu's so the odds of it going arcy sparcy are huge. I'm not going to spend one second fixing them either. I'd just use the current HV psu and add a separate delay line.

No problem supplying you with the Gerber files but this has never been tested.

It's the same thing as the KGSSHV but with two things added, a C- supply for amps such as the BATE and ESX and it has a delay circuit as well. That PCB is huge though...

Happy Birthday!!!

It was a joke given the crap LFF puts out...

Given how heavily censored I am at a certain other site there can be a counter argument to that...

Hifi News also has great measurements for DAC's so that's not really needed. They also measure headphone amps but only the UK stuff. Meridian Prime in the next issue but we all know it is shit...

I'm sure we can rustle up some crappy amps to measure against the good stuff.

Happy Birthday Ken!!

It can handle the short circuit for brief moment just fine. The Krell amps all shipped with TRS sockets...

The mafia obviously... I do think Tyll won't have it easy measuring amps as the worst offenders would never send their stuff in. Then we have the idiots who think there are some gray areas in amp design who will dismiss the good performers as missing "the magic". Now if Tyll can shame those that won't have their gear measured to do so then we would have real progress. I do think that the shills on HF will not take kindly to this though...

There has to be a better word than fragile but basically if the B22 shorts at any time then it roasts half the output stage. This makes TRS plugs almost impossible to use. KGSSHV, yeah the first ones were not user friendly but then again, nobody has ever made a mass DIY project at +/-500V so there were bound to be some issues. Still the final version (v1.0) of the PSU is promising.

Merry what ever suits you!!!

Now if we could only bring people to take amp measurements seriously too then we'd be golden. Perhaps it is time to put together something like this for amps based on the data we have at hand. I know the shills on HF wouldn't like it one bit.
