More music, that's good to hear, you're welcome!

Just wait till you try some low-noise regs and other fancy components...

Default ground plane

hi this may seem like a stupid question but im quite a noobie at this, if i make a circuit board for the output stage how would i fit it in the player, could i screw it down or will this mess up the grounding, if you know what i mean?

thanks

chris

Hi Chris,

You could screw it down, but most of the times there's no room for drilling fixing holes in the player's PCB without damaging the copper traces. Or you could short-circuit things with a metal bolt or nut. I usually glue a few distance studs to the underside of the PCB-to-be-added and then fix it to the main PCB with glue or small pieces of double-sided foam tape. Or I use tape on top of the HDAM cans or the electrolytics combined with some studs.

Regards,

Ray

At this latest creation, I use the HDAM cans as basis, then a layer of foam to keep the clearance and, at last, double sided foam tape to secure the circuit board.

Hi guys. I am looking to build a discrete stage and having read above about inductors picking up noise, would like to know the best ones to use. I am looking at:

1193619 and 1077043 , any ideas which are best? Or can one of you guys point me somewhere else for better ones?

Lee.

This one has lower resistance but same inductance

Hi,

I assume these are Farnell part numbers not RS ?

http://uk.farnell.com/jsp/displayPro...sp?sku=1077043

Cheers,

Jon

Yup, that they are. Any ideas on the best to use? I have just made these and want to get cracking.

Anyone, what's the best way to stop the boards oxidising?

Cheers, Lee.
