Thanks for the super cool documentation. Looks really great!

Thanks for all your efforts.

regards, tom

Dear Joachim,

it seems we all have to wait for the parts of the groupbuy, so I decide to begin with the enclosure.

I found the dimensions of the pcb's, but I have no idea how much space I have to leave for your pre-regulator, you wrote you will design.

Thanks a lot to all who make this possible,
Christoph

Hi Christoph,

Separate them.
The best way is to put the pre-regulator in its own box and away from the signals.😉

Hi Gandralf,

thanks for your advice, it is very welcome.

I'm not sure if it will work, but I will try to get the
paradise in a case like my Symasym and Hepos, the
three in same size and shape will probably be my
favourite.

I have about 40 x 32 x 8 cm free space inside the case,
it is made of steel with a front added made of wood.

A fourth case just for the transformators and the pre
regulator is only the second choice for me, but if it
will not work out the way I wish I have to follow your
advice.

Thanks in advance for any ideas or support,
Christoph

I am not ready building the preregualtor but on the MPP thread you find a well working circuit and also a PCB from Algar.

Still nobody soldering on the new Boards ?

 

[pdul]

only Germans for now🙂

Hi there
after populating those really cute Boards with Resistors
i do need some Spoon feeding about the LEDs.
I know ive been reading a lot about it in the MPP thread.
But it is long time ago since.
And i am an old man.
So
would someone please help me out with those facts ?

What do you need to know about the leds ?

 

[Benedetto]

Hello Riccardo
i do remember there were some advices about
what to do.
But i am too stupid to find em.
Ive got a bunch of them here and simply forgot the point.
I remember every chain has to drop some voltage ...
Btw
im shure im not the only one.

I think its 1.8v across each led with the long lead going to the markings on the circle on the pcb.I'm sure someone will correct me if I am wrong.

 

[pdul]

I used green 3mm leds

 

[pdul]

It pays to use brand leds. Some of those from fleabay have a very short lifespan.

 

[Benedetto]

long lead going to the markings on the circle on the pcb.

At least this much is crystal clear.
But i do foggy recall there was a value for every chain.
Sorry for picking...

Bought mine from world famous Buerklin. 😎

Well.... use only "normal" brightness leds because each one should drop around 1.8 ~ 1.9v.

Be carefull to place them correctly (one inverted led will prevent normal functioning)

The marking in the board indicates Anode (+) Long leg.

You can use low current leds.

IMO Lowest noise comes from yellow ones but red are also ok

Many thanks Ricardo, I was going to say the exact same things....

Has anyone found a good technique to keep the insulationpads in place while mounting the powertrannies, without the screws to help?😕🙂

 

[Benedetto]

What kind of pads do you use ?

Just tiny litle bit of heat transfer not needed with Kerafoll but one only has 2 hands.
