For Sale or Trade:
Dual mono OPUS, musiland 01usd

Will Ship To: CONUS

Relisting this. Had to close to ad since it did not sell before I had to head off to Maxwell AFB last summer. Relisted on 8/6/2013

 

 

First is my dual mono opus. I made this two summers ago, but need money for college now. It's been great for me, never had any issues with it. Its built with an SPDIF receiver to a metronome ARSC to dual wm8741 opus boards, to a BAL/SE output stage. I'm about 600-650 + shipping into this one, But I'll take 450 OBO shipped, Ill cover paypal fees

 

 

The parts that went into it are:

2 transformers - 15+15 30VA and 9+9 15VA.

Par metal case with filtered IEC inlet.

 

If there's interest in just the Musiland 01 USD usb to spdif I'll take 45 shipped for it, or else its included with asking price for the opus.

 

That's just the basics, more pictures and info will be up tonight.

 

If you want a picture of anything, want a measurement of anything, just ask.

 

Honestly on all my stuff make me an offer, worst I'll say is no.

 

Paypal preferred

From a safety point of view this build worries me.
I see a piece of flimsy electrician tape covering the terminal block.
The earth wire should make direct contact to the chassis, running it through the transformer bolt is not a great idea.
Did you use rubber mats between the transformers? Otherwise that's a potential short waiting to happen.
If your going to sell your DIY make positive it meets electrical standards.

The electrical tape covering the terminal block is totally superfluous, the safety would not be compromised with or without it. It was mainly for when I was taking multimeter readings so I would not accidentally rest my hand there.

Ground is ground as long as there is solid contact, which I have verfied with a multimeter. Ground does not care if it has to go through a foot of chassis or 2-3 inches of bolt and 10 inches of chassis.

There is a foam disk between the two transformers, they are not touching.

If you're going to critique a build, please be polite and take it up over PM instead of clogging the thread.
