It somehow slipped my attention that it's christmass 😀
To be hoenst, those boards took me forever to make, I have made 4 for myself (which are to be used for a 2 channel pre), and 2 raw boards without soldermask and not drilled for Steenoe.
Just the size of them presents a challenge, as all my PCB gear seems to have grown smaller over night 😉

Well, I can send you the PCB123 file if you care to make some yourself, or wish to order some from those guys.
Magura 🙂
Thanks Magura but I was really just kidding. But maybe not if you happen to have some extras.
Nice work as always from your side. Congratulations 😎

Never mind Steen guys 😉
He is just (fly)fishing for the matching PSU boards.
Those are CLC and regulated. That seems to bring the best possible.
I just got ferritic stainless steel for the cans for the inductors, waiting for the laser to be "off duty" for half an hour to cut it.

If anybody is interested I have a set of 750 Ohm Mills Audio Resistors for the original BOSOZ.
If anybody wants them I can give them for what I paid at Partsconnexion.
Just send me an email or post here.

Well I am still trading them...😀
Is anybody interested in a group buy for the parts?
A few people have asked me.
Till now I can organize Mundorf Caps, Mills Resistors and Panasonic Caps FC and M Series.

So, almost there, just lacking a couple of power resistors.

And finally done 😀 😀 😀 😀

The caps are mounted under the board to avoid turning them upside down, they don't like being upside down according to Rifa. This has a benefit though, as they can serve as stand-offs as well.

Hi Morten.
Very nice board layout🙂
Guess I have to build me a preamp like that.
I recognize a load of that hardware, but what are those Tampax thingies??😀 😀 Are you entering the ladies business😀 😀

Those tampax thingies are teflon foil caps from CRC. The resistors are russian military metal film. The blue caps are Rifa PHE 426 (but you already knew that). The power resistors are Phoenix metal oxide 3W. The electrolytics are Rifa 680uF PEH 169, and Rifa 22uF PEG 124.
The transistors are BD441 and the mosfets are IRF610.

Magura,
When are you going to put it all together?
I'll race you, I am about to start remodeling my bathroom, let's see who finishes first. 😀

Well, I have a naive hope that I will be done around Christmass.
So Grataku, how big is your bathroom ?? 😉
I have most of the Zen V7 ready for assembly.
The attenuator have had a test run, but I would like to implement a bigger PLC, to be able to use the PLC to control more of the system. So far the controls are limited to remote volume control, remote power up, and remote switching between 25 and 50V rails. The PLC is also monitoring the temperature and will shut down the system in case of overheating. To this I would like to add remote controlled source selection and to make a PLC controlled soft start for the power amps.
The BOSOZ is lacking 3 boxes and a PSU board, but neither of that should take long to get done with.
The big problem is that I have a couple of other projects running as well (surprise, surprise). I have a carbon fibre disc brake project (for cars) that has to be done before it gets too cold to test, in order to have them hit the market next spring, and modernizing a production line of a brewery.....and a regular job that takes like 50hrs.a week on top of all that
I will have to admit that the carbon disc brake project has taken first priority
to my amp project. I still get a kick out of going 0 to 200 km/h in like 9 or 10 seconds (though the initial feeling is wearing off by now), so cars seems a little more interesting for now, but as the winter creeps up on Denmark, I'm sure audio will get first prority again.
