I am still trying to find an accurate parts list to order the components.

I can build it in one night and be listening the next day if I can order the correct parts.

Just finished mine As it happened, I had a chassis like Tortello himself I fitted a heatsink in the bottom of it. It is running from a "pure breed" Zen regulator. Big caps are Black Gate's, input cap is a BC 4,7uF MKT. The sound is amazing I didnt use a pot for it, but runs the amp from my beloved BosoZ. I also had some rather tall feet machined for the chassis, to help the airflow around the heatsink. You can see the heatsink right underneath.
The amp is totally quiet in the headphones, with no signal. Only a little "mosfet hiss", with the volume at full throttle.
Thanks, Tortello for this fine circuit, and DIGI01 for the boards

steenoe-

I love the chassis.

Couple of questions:

1. Where did you get the chassis?

2. Why the heatsinks? Was the chassis it's self not enough to cool the amps?

I hope to finish mine soon, but I have been busy on my Krell Clone, Pass Mini-A, Hypex UcD-180's and the speakers all of them will be tried / used on...

I will try to post a picture of mine shortly. I have a chassis from Par-metal that will house a remote controlled input selector and volume control from DIYCLUB.biz, Pavels "audio refiner" (line stage) circuits, and a switch to go between Zangs headphone amp and BrianGT's LM3886 GC.

Although I may NOT implement Pavels circuit and save for a purist approach preamp later.
