ZV5 PS layout question

seventenths · 23rd May 2008, 11:24 PM

Salutations,
I'm working on a ZV5 stand-alone power supply and I have a layout question regarding the inductors.
Is coil placement and orientation critical in a stand-alone implementation? ?... somewhat critical? Are there any good rules of thumb to live by?

Thank you,
7/10

I don't have too much advice to offer...

But I built the amp exact as designed (bobo Zen V5), but for the power supply, I chose to experiment a little...as I didn't have all the required parts

I am actually using two 19VDC, 3.2A Laptop Switch Mode Power Supplies per channel (4 laptop power supplies total for 2 channels) feeding a pair of two 10,000uF caps/channel.

Sound seems clear and good. Nice compact build.

I guess if the power supply is clean and stable, try it.

Keep the coils away from the input circuit.

Thank you Gentlemen. As this is a stand-alone supply, I should be in great shape then
