It's a little difficult to spot - I added an image tag to the post..

Thanks for nice comments folks.

I'm so sorry folks. I promised you my w492 front panel files, but I've lost my memory stick. Argh, lost a few other things aswell..
Again, sorry folks. From now on I'll backup and backup the backup.

I am shopping for parts now... are Panasonic Polypropylene Film Capacitors, P-Series an overkill here?

What kind of caps do you recommend?

 

[mitsos]

I got all wima films (have to check which ones) and panasonic lytics from TAW.

Despite warnings I have decided to publish the PCB manufacturing documents of the W492 equalizer. I hope that it helps those who want to make their own boards. Documents are allowed to use only for DIY purposes.

Thx for sharing those Audiox

I spoke to audiox about this, and you will soon be able to get a parts kit for this project.

Cheers

Nice!

What caps do you plan to offer in the KIT?  ;D

Sounds great! Will it include the pots?

Ptown, if you do the kits with the Omegs, Laura at TAW has them. They are $18 a channel IIRC. Maybe you could cut a deal with her to take what she's got left over off her hands. Thanks for doing this by the way.

KIts???Wowwwww , nice!!!
Some W492 in 500 series??? 8)
At first sight should be doable , isn't it ??

IIRC Laura also have all the wima caps needed in here!

 

[buschfsu]

yes i was going to order to sets from laura but if you do the kits ill support.  ptown with this be on your site?

Any news on the kits?  Going to hit the buy button for 4 kits.  Thanks.  Mark

If I have understood right quite many are making their W492 with Omeg pots because of the lower cost than Sfernice. The problem is however that the section spacing of Omeg is 7.5mm (Sfernice has 5mm). Potentiometer pins can be bended but it is not very elegant solution...

It is not a big job to make an "Omeg" version of the pcb with 7.5mm spacing. If you are interested, please let me know.

I would still love to see this done since I'll probably end up etching a couple more of these. Thanks!
