Can you tell us where we can find the schematic this p.c.b based?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
Hi Shaan... thanksJohn! tthose cccurrves....
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
Hi Thimios,Can you tell us where we can find the schematic this p.c.b based?
I don't have the schematic
Look at Jason reply :
Thanks Jason,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<
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

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.

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

471 is 470 pf not 47.
It is 47pf ...tested471 is 470 pf not 47.
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 CCSThat 19v is that inside spec, myself too lazy seek the info .
