Just finishing my 800's and found out that I soldered C18, 19 and 20 in the WRONG positions!
Pay attention to that, it took me a day to find out!
Couldn't get to work..........
It's nice to have the option for different pitches but it got me fooled :mad:

Hi,

Two questions for the green psu for the s800:

Will this heatsink be big enough for running 8 channels (one for each regulator)?: http://www.musikding.de/Nuts-washers-screws/Heatsinks/Heatsink-19mm-22K-W::2108.html

And will this do the job as the 100nF caps on the green psu?: http://www.musikding.de/Passive-parts/Capacitors/Film-Capacitors/Arcotronics-MKT/MKT-0-1uF::521.html

I think the BOM links to polarized electrolytics, but the PCB does not show any ploarization, so I thought the MKTs might work? ???
 
Sorry for asking all these noob questions.. but are the caps in Collins kit marked with u1k = 100nF?
 
bump on the PCBs.  I would be interested in supporting the community by purchasing PCBs :)

Hi

Finally finishing this project off, it also happens to be my first. I just have one quick question.

Is it ok to use the on-on mini toggle switch that came with the audio maintenance for the power switch?

I read elsewhere on another site that mini toggle switches should be avoided for power switch situations.

Cheers!

Most toggle switches have a voltage and current rating printed or engraved into the body of the switch.

Have a close look and see if there is anything there.

Hi everyone.

My S800 boards are on the way, parts kit from AML is on the way.

Can someone recommend a power transformer? (230V primary) Brand names and places to order? I've had some bad luck with locally supplied rubbish recently.

I did read elsewhere that I can use Mnats power-supply board with the S800. (I've got one already) Has anyone had any luck with this?
If not can anyone give me an idea of where i would find a schematic, or even possibly a power-supply pcb that would be suitable?

Thanks!

Mnats Power-supply board that I have

I did also find a pcb layout for for the Green Pre PSU (I just want to confirm that this is a common option)

Which would be a better option if the Mnats board can be used?
 
PM me your phone number.

30Va or 50VA should be fine depending on how many channels. Bit more expensive but Nuvotem make good transformers.
