Feel free to swing by and listen to mine when you are in the Stockholm area. It will be fully loaded as soon as my metronome module arrives.

Hehe, does your iron ever cool down Mattias?

Sure if I have the time I would like to hear the OPUS, maybe I should bring my HD650 and try out the MAX/OPUS combo?

On that note, guess what this is for...

THAT transistor headphone amp (250ma discrete opamp) design sanity check.

Hi Brian,

I am thinking of buying the same 16x3" case from Par-metal, like the one you are using.

I will have them punch out a couple D-holes for Neutrik jacks on the back panel. Do you have drawings of your back-panel with dimensions, by any chance?

Thanks!

[BrianDonegan]

Actually, I used a 12x12x3 case. I have an eDrawings file of the rear panel (attached), which was milled from 3/8" plate.

Aha, would this thing be the same size as the rest of your stuff?

Cheers

That's what I am shooting for.

Hi Brian,

I did not see the attachment for rear panel drawings. Is it my Internet Explorer setting, or did you forget to attach it?

Thanks!

[BrianDonegan]

No, it's because I'm old...

(You'll have to remove the .txt from the name, and it *might* only open in IE (hope not))

[hbarki]

Hmmm... removed the .txt, but it refused to open using IE.

BTW - looks like you have a 16x12x3 case in this picture (Parmetal P/N 20-16123x):
