VSSA Through-Hole-PCB build thread

John! tthose cccurrves....

Ok, this some file...
yes the curves look a bit scary isn't it
(I hope nobody scared, no pun intended)

I'm just happing fun to create it

Can you tell us where we can find the schematic this p.c.b based?

 

[jkuetemann]

thimios,

It looks like John used the VSSA schematic in Lazy Cat's thread using more common parts, or at least it should be very close >HERE<

Hi Shaan... thanks
hehe I'm trying make some arts
not fully tested yet because the Cap. Multiplier is not finished yet
I'm still using the PeeCeeBee till now

Can you tell us where we can find the schematic this p.c.b based?

Hi Thimios,
I don't have the schematic
Look at Jason reply :

Thanks Jason,
Yes this one is the closest schematic but with some bigger parts that's available here at local store

BTW I'm just finnish two more boards but it is a PeeCeeBee based
the easiest one to build... I'm try to make it as little as possible
but no picture yet

Regards

Can somebody please tell me where and how Pete is?

He seem to be off for more than a year! Is he okay?

 

[Idefixes]

Pete Who?
The only Pete I know here is Pete Vogel (@ostripper).
And he is alive and kicking!

The "pete" Shaan is speaking is PMI the autor these topic.

[shaan]

Ok guys. Now I know. I hope he is okay.

 

[Idefixes]

Ok guys. Now I know. I hope he is okay.

I hope too, as he was always a nice guy during forum and PM/mail time.

I want to run this in mono mode.
Each channel powered with two laptop supplies,one for + rail and the other for - rail.
One channel (this with polystyrene compensation)run well ,just a little warm zobel,when the other(this with claim compensation) smoke the 10R gnd lift resistor and the zobel resistor .
Each channel tested separately,only one channel runs each time.
Scope show oscillations.
That isn't present when modules run from a linear power supply.
Opinions please

Hi thimios,
Is supply voltage level up to same value as the linear one.
Try invert live power connector feeding one of the laptop supplies.

471 is 470 pf not 47.

 

[thimios]

471 is 470 pf not 47.

It is 47pf ...tested
No,linear power supply is +/-35v when switch mode is 19v only

That 19v is that inside spec, myself too lazy seek the info .

I must measure the Vas current as input powered via CCS

Any news from PMI ?
I'd like to know where I can buy 6 boards shown in the first page... Thanks

 

[vgeorge]

Better forget it. PMI has vanished, it's some time now. I am still waiting for a couple of boards I payed.

 

[Raj1]

Yeah he bailed for whatever reason and never delivered what was promised to several of us. The amount of money involved was not huge, but that's beside the point.

 

[dady]

I think that PMI died. No friends here on Diyaudio.
How many of us have any friend in hard contact?
RIP PMI.

 

[manudrz]

Okay, don't know about PMI and how is he, any one of you have the Eagle files to reprint these boards ?
First I was waiting for the new rev of the official VSSA, but it seems that LC goes to a more commercial way...
