|Machined 304 Stainless Steel O2 Front Panel Rev. 2
||Buy one of my new Rev.2 panels directly from me! The panel and holes are laser cut from 304 stainless steel and the lettering/symbols are chemically etched into the surface of the panel and then filled in with a dark black paint. This yields a far nicer and more wear resistant appearance than the typical silkscreening or laser engraving processes used for most panels.
These panels fit the "stock" Box Enclosures B2-080 enclosure.

All sold as of 2/20/2013! I could have another batch made if there is enough demand but so far the batch of 20 has not been profitable for me and it doesn't seem like there is much interest. Be happy if you're one of the few people that managed to get one!
When I decided to build a batch of five O2 amps with my friends I, like many others, went to JDSLabs to order their aluminum front panels. When I got them, however, I was honestly rather disappointed - it looked all shiny and nice in the pictures on their website but the actual parts I received looked fairly lackluster and were rough around the edges. I wasn't a big fan of their company logo on the front panel of my DIY amp either. I decided to fire up my CAD program and look into getting some nice stainless steel panels custom machined for me...

This revision features chemically etched lettering and symbols filled with black oil-enamel paint and uses a #4 (brushed) finish rather than 2B. The panel material remains 304 stainless steel and it can be either waterjet, laser cut, or CNC milled depending on my supplier's capabilities.
Overall I think it is much nicer than the panels from either JDSLabs or Head 'n' HiFi though admittedly it's a good deal more expensive to manufacture as well.
Here are some images of my initial prototype batch of 20 with Kunshan Krell:
For a production batch of 100 I can easily hit a $12 price point. The main problem is that I never wanted to commit the investment for such a large batch since this isn't my full time job and I don't want to potentially end up sitting on a large pile of these.
I had originally meant for these to be produced on a larger scale, but they ended up costing over $30 each to make and community interest did not seem to be there. I went and had two of them machined anyway since a friend and myself each wanted one. The panel and holes were laser cut from 2B finish 304 stainless steel, and the lettering and symbols were subsequently laser engraved.
Here are some pictures of how it looks:
Sadly I scratched one of them a bit when I unpacked it with my knife, but luckily I able to patch things up somewhat by sanding the part down with 220grit sandpaper. It kinda has a brushed look to it now too.
Silly me needs to stop knifing everything...
