UGS Power : it's U.P.

[CeeVee]

..update:

it's ok François i checked the HCFR forum and put myself on the list there.

If a GB is created here i can always transfer my request to this one.


😉

My UGS preamp is going to have a gorgeous business end !!!


Thanks for outstanding work and generosity.

 

[Luke]

Yeah thanks, personally I can't see what was wrong with the old ones🙂

Does any one know if its been offered here on diyaudio? If not does anyone have a link on the french forum, I hope with a bit of Babelfish action I might be able to place an order and hope no one asks any questions in french🙂

Hi Luke,

Changes are minor but crucial as would be expected.

here is the link:

or try and track down some old school friends who took french😀

Thanks CeeVee🙂

Any info on the location of the groupbuy page would be greatly appreciated.

The above link is the GB page ( thread ) as i said before you will have to register to be able to add your name to the list on last page of thread.

cheers! Anywhere I can get a UGS pre pcb ?

[CeeVee]

There's a Gb same place...if you hurry you can still get in ...i think !!!

here is the

Both are very sophisticated projects...you will have your plate full until next summer........

 

[dhole]

That seems to be for relays not pcbs... Any chance someone could purchase a few for me ? ( the pcb not the relays)

Ok guys 😎

If you have any question because of your bad french feel free to ask me any questions. 😉 Anyway, please send me a pm for me to know who is from diyaudio in the GB on HCFR.

Thx

Hi all,

Some minor changes, mainly on the softstart board, to avoid potential problems with heated resistors on faultly reset due to µcuts on mains (lightning induced effects) 🙁 All is safe now 😉

Are there any foreseeable solutions to the JFET market problems ?

Don't worry ...
If needed, ZeeMee will certainly be so kind to translate it in Anglais ... as usual

I hate ya Frenchie boyz 🙁

besides other things - you have so many great great comics , and I understand Bahnhof Frenchy .....

Well ... I am happy to be proud ...
But I must admit that in case of UP and comics : me is nothing...

But mebbe you mean I should get the credits for "other things" ...

Cheff, Ive ordered the pcbs from the the french groupbuy.
I have a couple of Antek 400VA 20V torroids and Im simulating in duncans psu designer what the voltage will be. It seems that I may get close to 50 V on the voltage doubler end of things. Should I use 63V caps or will it be safe?

 

[CheffDeGaar]

Luke, is your voltage doubler loaded ? (Need to supply 50/60mA)

 

[Luke]

Cheff,

I havent got the boards yet, Im just in the process of ordering parts🙂
In fact Im not sure how the voltage doubler works.

 

[CheffDeGaar]

Luke,

I was just asking since the output voltage is lowered when the doubler is loaded :
From my 18V trafo, I measure 50V on the doubler unloaded, and 36/37V when loaded.
Thus, for your 20V AC input, it should give around a theoretical 55V (20xswrt(2)x2-Vdiodes) unloaded, so I think you should be safe, but try a sim with a loading resistor in order to draw 60mA.
And prepare to be surprised by the ripple 🙂

 

[Luke]

Thanks Cheff,

I think you've answered my question. I will use the standard BOM and my anteks. They seem to have a good rep and they will give me a bit more power🙂
