Also q.q why do so many Dacs also have AMPS in them... NO ME GUSTA [thanks  odac fo rur purity] but looking at P-H I wished I'd gotten one...
Those are amp/dac units. You are looking or dac unit. Its like asking why there is cheese in a cheeseburger. A hamburger is also a choice.

I think you can sell plenty of them at the mingo headphone expo thing in HK if you want economy of scale...

(Did I give you sockets for them?)

Current flows from the side without bar to the side with bar.

Yes, just follow the diagram.
Why's that?

Unfortunately you didn't LOL. Oh well.

But which side should the side with bar be?

Wokey

Haven't been around in ages, schools been killing me. But after my major exam on Wednesday, I'll be around a lot more often.

How's everyone been?
Good! A few of us will be meeting up a bit later in Seattle! biggrin.gif

It's the latter, but I do remember it...

It sounds noisy......

Here's a more interesting P-T progress report:
PCB done, its 10" x 4"















Listening to "No Distortion!" by Samfree feat. 初音ミク while designing an amplifier, how appropriate biggrin.gif
That's a pretty big PCB! eek.gif
Looks like a fun build though!

lol ok, thanks biggrin.gif

I think we can do a group buy on this if there are people interested, because most of the discrete components have a minimum order and the per unit cost decreases quite a bit if we buy in bulk.
Ooh, that sounds like a good idea! biggrin.gif

So now the question is: who will finance this? Finance 10 full units to see profit.

Financing seems to be $1000USD for approx 10 unit if all costs from pcb, parts, case, everything to finish minus working time costs is about $100 a unit(case is expensive)

Get me a quote.

How many units are going to be made for this show. Are you selling there? How Much for a fully assembled unit minus workingcosts.

It's shown on the diagram.

Well, it's a speaker amp.

Oh btw, the power can be scaled up even further by using a higher supply voltage,

Given a sufficient power transformer and the caps can withstand the voltage, it can output 2x 50W no problem.

That sux. Would be nice to get some
B1O Labs love.

But remember. Currawong is watching

Lol jk. He is quite amused we even made
A unit

I can only get you the stuff on the PCB for now, we haven't decided on the case and stuff.

This excludes:

  • Power connector
  • Power switch
  • Power transformer
  • Power LED
  • Volume Knob
  • Gain switch
  • Headphone connector
  • Input connector
  • Case

 

I'm working on the BOM right now, give me some time....

I asked him if I could post my review on it. An he said to do whatever. He found it hilarious the anime threa even made a unit.

Oh the PCB cost is not factored in either.

 

It turns out to be US$55 in components only.

How much is 10 PCBs?

How much is the case you will be using?

To reduce costs, no need for engraving or silk
