Thanks for all your kind words!

You've got to give more details on how that's done - the etching of lettering on there and stuff.

I laid out the design in Pro/ENGINEER (made a 3D model to make sure everything would fit), then exported the part drawings to AutoCAD and plotted the design directly to a laser cutter in the machine shop at school. The etching is done the same way, using slightly higher speed so that the laser only cuts through halfway.

If you have access to a laser cutter at school or work, it's a nice, fast, cheap way to get good looking results!

That looks wicked, I was hoping to do something similar with a PPA in a hammond

Unfortunately, laser cutters aren't generally put in every college! </dremel action>

Here's my PPA, it's amost 100%. I need a better volume knob and I need to put the NIMHs in. Otherwise, it works great from wall power.

My switches allow me to Change Gain from roughly 6 to 12. I have a crossfeed switch, and of course the Bass Boost.

Here's the back:

__redruM: Very neat and tidy! Where you get the lettering done on the panels?

Label maker at work. It prints Text on Clear plastic stickers. Which I applied.
Thanks for the comment...

if you guys want custom labelling you should check out local decal places, i got a quote on a project from one near me, and it was really cheap and u could choose whatever font you wanted. just apply decal then clearcoat

also check local industrial engravers, my local one turned out to be dirt cheap and my friend at an engineering firm says they do a grade work.

I finally finished my 2nd pimeta that I rebuilt with an Alps stepped attenuator. It sounds brilliant. I did not think that it would make such a difference. It was my first stepped attenuator, so I decided to socket all of the resistors in case the attenuation curve was not to my liking. I also had to learn how to deal with momentary switches and debounce. All in all, it was a satisfying educational experience. I will now try to determine were to put it.
