Hi Folks,

I'm about to embark on my first serious build. I've built a few guitar pedals however this is my first mains powered project.

I'm interested in building a stereo Neumann W492 EQ. I bought a couple of PCBs a while back so the first thing I need to sort out is the components.

I have a few questions:

1. On page 36 of the build thread there's a Mouser parts list - has anyone checked this? Was a Mouser cart ever created for this?

2. I've read that the pots are hard to get. Are the following (recently mentioned in the thread) the right pots? Will one of these two fit the PCB better than the other?

3. I can't find any info regarding the PSU - any recommendations? PCBs? Kits? Would one of the following power supply kits and transformers be suitable?

Cheers,

Hi Chris

I am about to build a w492 clone as well just wondering if the transformer from jaycar and the psu was good enough for your build?

Cheers
