Fits well into the Zippo, the PCB design was originally by Guzzler, built using a home etched PCB, with rail-splitter and opa2132pa op-amp.

[IMG]http://[/IMG] Hi everyone,

Well after a little trouble with the volume led ring (my fault) my PPA is up and running.
Once it's run in i'll think about diamond buffers, biasing and crossfeed.




I'm really proud of the case, it's the first one i've made and nearly turned out as i'd intended. I'm currently running it from the onboard sound of my pc and it sounds great. The next stage is to build a custom pc into a similar chassis with an RME soundcard, mount a behringer dcx2496 into another similar box and finally build some similar looking gainclone power amps. I'll finally have the system i'll be happy with (i think ).

Selexus...
The case looks cool, but the middle knob reminds me the
Griffin PowerMate

Nice though?

I wondered if anyone would pickup on that . I had a couple of the powermates (in silver) floating around. After disassembley i found that the only part that i could use was the clear diffraction ring. So i made the Ali/copper knob and base, and cut some prototyping board to fit and soldered the leds in.

I was given a metal forming machine last Xmas (tools for Xmas...yes please), it cuts folds and rolls sheet up to 1.2mm. The case lid is my first results from it

cheers

I had some black left over after spraying my bike so i used that. I'm really unhappy about the primer though. I didn't have any etch primer, so i used regular...big mistake. It flakes of realy easily, so i might have to strip it and do it properly

Very exotic casework there, Selexus. Congratulations. Are those two copper-colored tubes strictly cosmetic? Do they contain anything?

The power transformer looms rather close to the input circuitry on the PPA board, though. Do you notice any induced hum?
